Cyclic plastic strains are analyzed for the pressurized elbow subjected to symmetric out-of-plane bending with finite element method (FEM) and the assumption of elastic-perfectly plasticity (EPP).

Endochronic plasticity based on non-yield surface is deduced into the displacement-based finite element method and the plastic strain direct method is proposed for the plane stress problem.
