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