| Abstract: | Dual variational extremum principles for rate problems of classical elastoplasticity at finite deformation are studied in Updated Lagrangian rate forms. It is proved that the convexity of the variational functionals are closely related to a so-called gap function, which plays an important role in nonlinear variational problems. |
