| Abstract: | Based on the irreversible thermodynamics and the internal variable theory, the elastoplastic model for isotro-pic damage and mixed hardening(isotropic hardening mixed with kinematic hardening) is considered. According to the generalized normality rule, the tangent stiffness operator of elastoplastic material coupled with damage is derived from the state potential and the dissipative functions. |
