Determining of the Fatigue Crack Growth Rate of HSLA Steel at Room Temperature
Апстракт
Welded joint is a critical region of a welded structure and fracture mechanics analysis is inevitable
in the structural integrity assessment of all welded structures. This paper shows the determining of
parameters of the fatigue crack for constituents of welded joints produced of high strength low
alloyed steel. The applied methodology refers to the Paris relation where the link was established
between the 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 ΔKth and parameters in the Paris’ equation.
This is mostly expressed when determining growth parameters of the fatigue crack in heat affected
zone of HSLA steel, where different changes of growth speed of the fatigue crack clearly express
differences in structure of the crack pass
