HSLA Steel - Simulation of Fatigue

In present paper, based on the results of the experimental study of the behaviour of the samples made of a HSLA steel, in the form of round smooth specimens (RSS) under LCF conditions (with controlled and completely reversible strain Δe/2 = const, Re = emin/emax = −1, according to ISO 12106: 2003 (E)) and square specimens (SqS) under conditions of HCF conditions (with controlled one-way variable load on tension with σmin = const, according to ISO 12110-1:2013), a computational stress analysis was performed using the FE method and the behaviour of this steel in the fatigue behaviour simulation (LCF and HCF) in SolidWorks programme was shown.
