Experimental verification of two-parametic models of fatigue characteristics by using the tests of S55J0 steel as an example

Abstract

This paper presents experimental verification of models of two-parametric fatigue characteristics N(σa, σm) on the basis of results of fatigue tests of specimens made of S355J0 steel. On the basis of comparative analysis of results of computations and fatigue life tests of the specimens, performed under constant amplitude sinusoidal loads of different cycle asymmetry ratios, the most versatile models were distinguished. The tests in question were carried out in the high-cycle fatigue range.

Keywords:

two-parametic models, fatigue characteristics, tests of S55J0 steel, computations, fatigue life tests, high-cycle fatigue range
