AB  - Topic of this work is the integrity assessment of the pipeline section from hydropower plant Pirot. Crack-like defect size, maximum depth, is determined based on non-destructive evaluation - the largest crack depth is taken as the initial value for load carrying capacity estimation. Also, the crack dimensions (both length and depth) are varied. Limit pressure values are determined from 3D and 2D models of pipes with axial cracks on external surface. The influence of tensile loading on the load carrying capacity of the pipes with circumferential cracks is also examined. Integrity of pipes with both types of defects (axial and circumferential) is assessed through application of FAD diagrams.

AB  - Vertical Kaplan turbines with nominal power of 176 MW manufactured in Russia are installed in 6 hydroelectric generating sets at hydro power plant 'Djerdap 1' (Kladovo, Serbia). Most of the components are made of materials in accordance to GOST and ASTM standards. During rehabilitation of hydroelectric generating set, the analysis of the current state and integrity assessment of turbine regulation system pipeline required non-destructive tests on parent material and welded joints between pipes and pipes-elbows. The purpose of the regulation system, comprising of the pipeline for the turbine regulator oil supply, is to open and close vanes of the guide vane apparatus and to regulate the position of runner blades and their number of revolutions. Internal pressure in the regulation system is p = 4 MPa. Structural integrity is a recent scientific and engineering discipline which in broader sense comprises state analysis and behaviour diagnostics, service life assessment and rehabilitation of structures, meaning that beside the usual situation where structural integrity assessment is required when flaws are detected by non-destructive testing, this discipline is also includes stress state analysis. This approach is especially important for welded structures, since cracktype flaws can originate from welding and from unfavourable service conditions. In this paper, the results of non-destructive tests referring to the lack of penetration in roots of butt-welded joints between pipes and pipes-elbows, as well as tensile test results of technical specimens with reinforcements and in specimens with parallel machined sides and standard dimensions, are presented in order to carry out the integrity assessment of the turbine regulation system pipeline of hydroelectric generating set A6 at hydro power plant Djerdap 1. Results of analytical strength calculation of butt-welded joints between 2 pipes, and pipe-elbow with a lack of penetration in the root are also presented.

AB  - This paper presents experimental and numerical analysis of the change of temperature and force in the vertical direction during the friction stir welding of high-strength aluminium alloy 2024 T3. This procedure confirmed the correctness of the numerical model, which is subsequently used for analysis of the temperature field in the welding zone, where it is different to determine the temperature experimentally. 3D finite element model is developed using the software package Abaqus; arbitrary Lagrangian-Eulerian formulation is applied. Johnson-Cook material law and Coulomb's Law of friction are used for modelling the material behaviour. Temperature fields are symmetrical with respect to the welding line. The temperature values below the tool shoulder, i.e. in the welding zone, which are reached during the plunge stage, are approximately constant during the entire welding process and lie within the interval 430-502 degrees C. The temperature of the material in the vicinity of the tool is about 500 degrees C, while the values on the top surface of the welding plates (outside the welding zone, but close to the tool shoulder) are about 400 degrees C. The temperature difference between the top and bottom surface of the plates is small, 10-15 degrees C.

Incompletely filled groove is examined, because this type of defect was previously detected by ultrasonic measurement on the inner surface of the pipeline from a hydro-power plant. Three-dimensional finite element analysis is conducted using Abaqus software package. The influence of weld defect geometry (its depth, length and location) on the elbow integrity is determined. Additionally, decrease of load carrying capacity is determined for the case when a crack has initiated at the bottom of the defect. The influence of finite element type (hexahedral or tetrahedral) is examined.

The testing results of tensile characteristics, hardness, toughness via instrumented Charpy pendulum, microstructural analysis and fatigue crack growth resistance of all characteristical zones are analysed in details, especially from the point of view of interaction between microstructure and properties. Obtained results indicate superior properties of repaired welded layers, due to their similarity to the new generation of bainitic steel, i.e., due to change of microstructure from original pearlitic structure to final bainitic structure. Finally, fatigue crack growth parameters have shown that deposite layer has higher resistance to the crack growth, improving overall reliability of rails and crossings.

AB  - Bucket wheel excavators for continuous exploitation belong to the modern, complex and expensive
production systems, manufactured in small series or individually for certain operating environment. During
exploitation of bucket wheel excavators, as an effect of variable amplitude loading induced by working conditions and
their own low-frequency oscillations, unpredictable failures (damages and fractures) of main parts and assemblies may
occur. In this paper, the methodological approach to the analysis of failure of the digging subsystem has been presented
with particular attention turned to the driving reducer for bucket wheel. The possibility of application of experimental
methods in an analysis of condition of the main parts and assemblies in exploitation and failure analysis has been
presented, together with the possibility of application of the methods in failure analysis from the point of view of
evaluation of the system reliability (FTA method – Fault-Tree Analysis, FMEA method – Failure Mode and Effects

abstract = "Bucket wheel excavators for continuous exploitation belong to the modern, complex and expensive
production systems, manufactured in small series or individually for certain operating environment. During
exploitation of bucket wheel excavators, as an effect of variable amplitude loading induced by working conditions and
their own low-frequency oscillations, unpredictable failures (damages and fractures) of main parts and assemblies may
occur. In this paper, the methodological approach to the analysis of failure of the digging subsystem has been presented
with particular attention turned to the driving reducer for bucket wheel. The possibility of application of experimental
methods in an analysis of condition of the main parts and assemblies in exploitation and failure analysis has been
presented, together with the possibility of application of the methods in failure analysis from the point of view of
evaluation of the system reliability (FTA method – Fault-Tree Analysis, FMEA method – Failure Mode and Effects
Analysis). The measures for prevention of damages and fractures of the main parts and assemblies of the driving
reducer have also been presented.",
