Estimation of Low-Cycle Fatigue Curves of High-Strength and Welded Steel 10CrNi3MoV

摘要

In this work is tested applicability of the extended uniform material law for high-strength steelon 10CrNi3MoV steel and its weld. Predicted low-cycle fatigue curves differ significantly from themeasurements. Despite the reported scientific effort to predict fatigue properties numerically, resultsshow that strain controlled fatigue tests must be conducted for determination of fatigue properties inthe praxis.
