"WebThe combined isotropic/kinematic hardening model is an extension of the linear model. It provides a more accurate approximation to the stress-strain relation than the linear model. It also models other phenomena—such as ratchetting, relaxation of the mean stress, and cyclic hardening—that are typical of materials subjected to cyclic loading.
