Prediction of Cyclic Residual Stress Relaxation by Modeling Approach

Abstract:

A new method for prediction of residual stress cyclic relaxation has been developed and implemented in the finite element software Abaqus. The calculated profiles were validated by experimental measurements using X-ray diffraction method. This validated approach is afterward used to investigate the effect of loading path and initial residual stress characteristics on the kinetics of relaxation and the stabilized profile for both cyclic softening and cyclic hardening materials.
