Bounding theorem in finite plasticity with hardening effect

Yang Gao, Tomasz Wierzbicki

The complementary variational problems for finite plasticity with strainhardening effect are developed in this paper based on the theory of convex analysis. A new lower bound theorem for the load intensity factor, in which the plastic yield condition is relaxed by a complementary plastic superpotential, is proved. A simple illustrative example is worked out.
