AB  - Most serious weldment failures have catastrophic consequences in terms of damage to other equipment,
loss of production, and risks to worker health and safety. For the above reasons, there is a tendency to find the
line between safety and disaster, and this requires a guarantee of the integrity of the welded structure even if a
crack is present.
The structural and mechauical heterogeneity of a welded joint affects its resistance to cracking in both the
elastic and plastic regions. Therefore, it is important to define the test method and the position of the fatigue
crack. The behavior of an elasto-plastic material, during stable crack growth can be described by the J-1\a
diagram. As the crack propagates, a point on the curve is defined, which represents the critical value of the Jintegral.
The aim of this experiment is to determine ne value and the procedure is reflected in the
determination of the R curve, i.e. the J-1\a curve, which consists of the value of the J integral for uniform
crack increments 1\a. In this paper, two SEN(B) specimens with the fatigue crack in the parent material (PM)
and weld metal (WM) were tested according to standard ASTM El820 at room temperature (RT) as well as
three specimens with the fatigue crack in the weld metal (WM) at RT, -20C, -30C.

AB  - The behavior of steel in low-cycle fatigue (LCF) is tested experimentally, in accordance with ISO 12106:2017 (E) and/or ASTM E 606-04. For this purpose, smooth specimens which are exposed to low-cycle fatigue at several levels of regulated strains and/or loads at room, elevated or reduced temperatures are used. Stress–strain response at LCF has the shape of an ideal hysteresis loop. The strain range Δε corresponds to overall loop width, while the stress range Δσ corresponds to its overall height. The paper presents a method for determining the intersection of the idealized hysteresis loop and the positive part of the strain axis in order to determine the values of elastic, Δεe/2, and plastic, Δεp/2, components of the strain amplitude to characterize the behavior of steel under low cyclic fatigue. The values of elastic and plastic components of the strain amplitude are needed to determine the characteristic curves of low-cycle fatigue, which describe the behavior of steel under the loading of low-cycle fatigue.

AB  - The most important characteristics for service safety of welded joints are those describing crack initiation and growth caused by variable loading. Crack initiation and growth caused by variable loading is the subject of numerous investigations. This paper shows the determination of parameters of the fatigue crack for constituents of welded joints produced of high strength low alloyed steel. The crack growth law of Paris establishes the relation between the applied variable load quantity or the corresponding stress intensity factor range and crack growth per cycle. Results have shown that the position of the notch and crack initiation affect the values of the stress intensity range of fatigue threshold Delta Kth and parameters in the Paris' equation.

AB  - Due to its superior strength at high temperatures P/T91 steel is often applied in the chemical, petrochemical and fossil-fired power generation industries. The high strength is achieved by a suitable martensitic microstructure after appropriate heat treatment procedure. Welding is the most important process of joining the components in such plants, and the heat-affected zone is often the weakest part of these structures. Having in mind that the welded joint is the weakest area, it is necessary to know its properties and assess the level of its degradation. It was found that the life-limiting factor in case of P/T91 steel welded structures are the cracks located in the heat affected zones, more precisely in its intercritical region. In present paper the results of the fracture toughness measurement carried out on simulated P91 steel ICHAZ specimens produced using a weld simulator has been presented. The tests were done on two types of simulated specimens, those subjected to the subsequent PWHT and with those left untreated (without PWHT), at room temperature and 600 degrees C. For the J-integral estimation pin-loaded SEN(T) specimens were tested in plane stress conditions using the unloading compliance method of deriving a single specimen resistance curve and the eta-method.

AB  - Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull structures have always been examined thoroughly. Cracks are most commonly initiated at locations where stress concentrators exist. These concentrators can originate due to flaws that occur during the design phase or due to mistakes that occur during the assembly of the structure. When it comes to failures and damages that occur at ship structures, it has been noticed that damages due to brittleness practically always happen at low temperatures. Impact test analysis is significant due to the fact that it replicates the ductile to brittle transition of steel in practically identical range of temperatures for all ship structures. Impact of ductile-brittle transition temperature is an important factor especially because there have been many ship failures and damages in history. In ship structures made of welded joints of high strength low-alloy (HSLA) steels with their segments (parent metal, weld metal and heat-affected- zone), the toughness test determines the tendency of steel to brittle fracture, respectively the tendency to increase brittleness during exploitation. Parameters obtained by testing the properties of plasticity are the fundamental for the composition of ship structures with the aim of realize strengths under tested load. The test results of high strength low-alloy steel toughness assessment at different test temperatures show that temperature significantly affects the impact toughness of steels and their alloys.

Brittle damages that occur on hull structures have always been examined thoroughly. Cracks are most commonly initiated at locations where stress concentrators exist. These concentrators can originate due to flaws that occur during the design phase or due to mistakes that occur during the assembly of the structure. When it comes to failures and damages that occur at ship structures, it has been noticed that damages due to brittleness practically always happen at low temperatures. Impact test analysis is significant due to the fact that it replicates the ductile to brittle transition of steel in practically identical range of temperatures for all ship structures. Impact of ductile-brittle transition temperature is an important factor especially because there have been many ship failures and damages in history. In ship structures made of welded joints of high strength low-alloy (HSLA) steels with their segments (parent metal, weld metal and heat-affected- zone), the toughness test determines the tendency of steel to brittle fracture, respectively the tendency to increase brittleness during exploitation. Parameters obtained by testing the properties of plasticity are the fundamental for the composition of ship structures with the aim of realize strengths under tested load. The test results of high strength low-alloy steel toughness assessment at different test temperatures show that temperature significantly affects the impact toughness of steels and their alloys.",

AB  - Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between safety and disaster. This necessitates guaranteeing the integrity of a welded structure even if a crack is present. Therefore, influence of the material inhomogeneity and residual stresses on deformation and fracture behavior needs to be described precisely. Fracture mechanics parameters J - integral and CTOD have attracted great interest in recent years. Two three point bending specimens of base metal (BM) and weld metal (WM) were tested according to standard BS EN ISO 15653. Than, a two dimensional finite element analysis was performed in Ansys Workbench software to calculate J-integral, and compare with experimental results. The aim of this work is to explore the possibility of using the test results in the reliable prediction of weldment fracture.

AB  - In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked pipes. A finite element method was used to calculate the fracture behaviour of the pressurized pipeline made of 14MoV6-3 steel based on the J-integral computation. The J-R curves were experimentally obtained by the elastic unloading compliance method for the single edge notched bend specimens and compared with those obtained using finite element method. A two dimensional finite element analysis was performed in Ansys Workbench software to determine the stress distribution and calculate J-integral values for the selected specimen geometry. Special attention was paid to the influence of applied boundary conditions on the accuracy of J-integral values, as well as to the influence of mesh density. It is shown that numerically obtained J-values significantly depend on the number of nodes used to apply displacements. However, if recommendations proposed in this paper are implemented, the accuracy of calculated values is satisfactory and successful failure analysis can be carried out. This approach can be useful in engineering applications where time saving and costs reducing are required.

AB  - Steel grade 14MoV6-3 is a low-carbon microalloyed steel with addition of chromium and molybdenum. This grade is designed mainly for power industry applications, withstanding operating at elevated temperatures.In this paper, mechanical properties of steel grade 14MoV6-3 and methodology of calculation of critical values of the J-integral are presented. The level of damage is determined by analyzing the virgin material of the same grade. The focus of presented investigation is on the experimental J integral determination, where critical values of the J-integral (J(IC)) are compared with the values obtained by using the finite element methods (FEM). FEM model was defined on the basis of experimental conditions and obtained numerical values should confirm our experimental results.

AB  - U radu je analizirano eksperimentalno istraživanje ponašanja niskolegiranog čelika povišene
čvrstoće (HSLA) u uslovima niskocikličnog zamora (LCF), sa kontrolisanom i potpuno
reverzibilnom deformacijom (/2 = const, R = min/max = -1). Ispitivanja niskocikličnog
zamora obavljena su na seriji glatkih epruveta od čelika Nionikral 70 (NN-70), sa
poluamplitudom kontrolisane deformacije, /2=0.35, 0.45, 0.50, 0.60, 0.70 i 0.80. Za izbor
stabilizovanih histereza i obradu rezultata ispitivanja niskocikličnim zamorom, korišćene su
preporuke standarda ISO 12106:2003 (E) i ASTM E 606-04, kao i dve nove metode: Metoda
sredine stabilizacije (MSS) i Metoda praga NDT (MpNDT), što u ovom radu predstavlja četiri
rezultata za poređenje. Za svaki nivo deformacije izabrane su karakteristične stabilizovane
histereze, određene prema preporuci standarda ISO 12106:2003 (E) i ASTM E 606-04, MSS i
MpNDT, sa kojih su očitani potrebni podaci za dalju obradu rezultata i konačno, konstruisanje
karakterističnih krivih niskocikličnog zamora. Konstruisane krive su međusobno poređene, a
ocenjen je uticaj izbora karakterističnih stabilizovanih histereza na karakterizaciju ponašanja
čelika NN-70. Rezultati eksperimentalnih ispitivanja su nam dali važne podatke o razumevanju
zamornog ponašanja čelika NN-70. U radu je izvršeno i poređenje rezultata statičkog i
dinamičkog, odnosno monotonog i zamornog ponašanja materijala, što predstavlja praktični
doprinos oceni ponašanja čelika NN-70 u uslovima delovanja niskocikličnog zamora.

stabilizovanih histereza i obradu rezultata ispitivanja niskocikličnim zamorom, korišćene su
preporuke standarda ISO 12106:2003 (E) i ASTM E 606-04, kao i dve nove metode: Metoda
sredine stabilizacije (MSS) i Metoda praga NDT (MpNDT), što u ovom radu predstavlja četiri
rezultata za poređenje. Za svaki nivo deformacije izabrane su karakteristične stabilizovane
histereze, određene prema preporuci standarda ISO 12106:2003 (E) i ASTM E 606-04, MSS i
MpNDT, sa kojih su očitani potrebni podaci za dalju obradu rezultata i konačno, konstruisanje
karakterističnih krivih niskocikličnog zamora. Konstruisane krive su međusobno poređene, a
ocenjen je uticaj izbora karakterističnih stabilizovanih histereza na karakterizaciju ponašanja
čelika NN-70. Rezultati eksperimentalnih ispitivanja su nam dali važne podatke o razumevanju
zamornog ponašanja čelika NN-70. U radu je izvršeno i poređenje rezultata statičkog i
dinamičkog, odnosno monotonog i zamornog ponašanja materijala, što predstavlja praktični
doprinos oceni ponašanja čelika NN-70 u uslovima delovanja niskocikličnog zamora.",

AB  - Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) = -1) has been analysed. LCF tests are performed on a series of smooth bar shaped specimens, 11 x 11 x 95 mm, parent metal (PM), welded joint (WJ) and simulated heat affected zone (SHAZ) of steel Nionikral 70 (NN-70) with semi-amplitude of controlled strain, Delta epsilon/2 = 0.40- 0.80. The results of the experimental investigation have given us important information on the understanding of fatigue behaviour of steel NN-70 and its welded joints. In this work the results of static and dynamic-, that is monotonous and fatigue behaviour of the material, are compared, which is a practical contribution to the assessment of the behaviour of PM and WJ of steel NN-70 exposed to effects of low cycle fatigue, i.e. monotonous and fatigue behaviour of the material.

AB  - In present paper, the experimental research of the behaviour of high-strength low-alloy steel (HSLA) exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon = epsilon(min)/epsilon(max) = -1) has been analysed. Low-cycle fatigue tests were performed on a series of smooth specimens made of steel Nionikral 70 (NN-70), with semi-amplitude of controlled strain, Delta epsilon/2=0.35, 0.45, 0.50, 0.60, 0.70 and 0.80. Characterization and description of the low-cycle elastoplastic behaviour of the material by construction of characteristic curves of low-cycle fatigue are made using the characteristic hysteresis, load-strain force for each level of controlled strain, selected from the areas of stabilization. For the selection of stabilized hysteresis and processing of the results of low-cycle fatigue tests the recommendations of the ISO 12106:2003 (E) and ASTM E 606-04 standards were used, which in this work means to compare the two results. For each strain level characteristic stabilized hysteresis were selected, determined in accordance with recommendations of the ISO 12106:2003 (E) and ASTM E 606-04 standards, from which the data necessary for further processing of the results and finally for the construction of characteristic curves of low cycle fatigue were read. Constructed curves are compared, and the effect of selection of the recommendations from the standards on characterization of the behaviour of steel NN-70 estimated. The results of experimental investigation have given us important information on the understanding of fatigue behaviour of steel NN-70. In this work the results of static and dynamic, that is monotonous and fatigue behaviour of the material, were compared, which is a practical contribution to the assessment of the behaviour of steel NN-70 exposed to the effects of low-cycle fatigue, i.e. monotonous and fatigue behaviour of the material.
