摘要

The current work is devoted to optimizing the Chaboche kinematic hardening parameters via an algebraic method based on its integral equations, which is rarely investigated. An experimental test in strain range of +/- 0.8% for 304 stainless steel (304SS) is applied to demonstrate this method. Firstly, the first quarter tensile part, along with the Osgood-Ramberg equation, is used to estimate the initial parameters. Then, optimizations are conducted based on the first quarter tensile part for the first and the 150th cyclic test. Results indicate that:
