Elastic-plastic analysis of notched structures under synchronous cyclic loading

This paper focuses on analysing the elastic-plastic stress-strain behaviour at the failure-critical location of notched components and structures under multiaxial synchronous cyclic loading. For this, various load configurations are investigated numerically consisting of constant and cyclic load components with constant and variable amplitudes. The von Mises yield criterion and the kinematic hardening rule. of Prager and Ziegler describe the elastic-plastic material property. The finite element software of ABAQUS is used to solve the boundary element problem. A parametrical study is carried out and numerical results are presented to show the effects of load amplitude, mean load and spectrum shape on the local stress-strain paths.
