Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma / Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters
(Institut za ispitivanje materijala, Beograd, 2012)
U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. ...
Identification of low cycle fatigue parameters of high strength low-alloy (HSLA) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (HSLA) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Cavitation damages morphology of high-strength low-alloy steel
(Faculty of Metallurgy, 2016)
This paper presents the research into behaviour of HSLA steel affected by cavitation. The parent material (PM) and simulated heat-affected zone (SHAZ) were studied. Ultrasonic vibratory cavitation test was performed in ...
Methodology for determining the region of stabilization of low-cycle fatigue
(Fakultet strojarstva i brodarsta, Univerzitet u Zagrebu, Hrvatska, 2016)
In present paper, the behaviour of high-strength low-alloyed (HSLA) steel under conditions
of low-cycle fatigue (LCF) has been experimentally tested and analyzed. Based on the experimental
results obtained in the programme ...
Determination of polynomial depending between hardness and cooling time t8/5 of steel NIONICRAL 70 heat affected zone
(18th International Conference on New Trends in Fatigue and Fracture NT2F18, 2018)
Because of the high heating and cooling velocity values, welding procedure is an unstable process. During
welding, changes in microstructure are occurring under overheating and/or cooling conditions. In comparing to ...
Assessment of the behaviour of fatigue loaded HSLA welded steel joint by applying fracture mechanics parameters
(New Trends in Fatigue and Fracture NT2F12, Brasov, Romania, Proceedings, 2012)
In discussion of the welded joints from fracture mechanics point of
view, it is assumed that the welded joint is pre-cracked and that therefore fatigue life
of the pre-cracked structure is determined by the period of ...
