Abstract

The subloading surface model has been formulated and applied to the prediction of cyclic loading behavior of metals. Furthermore, the return-mapping for the subloading surface model has been formulated and used in order to obtain high calculation efficiency in the whole loading state. In this article, the return-mapping in cutting-plane projection is extended so as to describe the cyclic stagnation of isotropic hardening to make the accurate prediction of the cyclic loading behavior. Then, the validity and efficiency of this algorithm for the description of cyclic loading behavior of ductile cast iron are verified by comparison with the test data.
