Large scale validation of a new isotropic hardening law for the barcelona plastic damage model under ultra low cycle fatigue conditions

Abstract

This paper presents the results of finite element simulations made on a bent pipe subjected to an in-plane variable cyclic displacement combined with internal pressure. The results of the numerical analyses will be compared to experimental ones. The constitutive model used for the simulation of Ultra Low Cycle Fatigue (ULCF) loading and the hardening–softening law used are only briefly touched upon. Special emphasis is put on the correlation between the failure mode and the internal pressure applied.
