| RATE VARIATIONAL EXTREMUM PRINCIPLES FOR FINITE ELASTOPLASTICITY | |
| 作者姓名： | 高扬 |
| 摘 要： | Dual variational extremum principles for rate problems of classical elastoplasticity atfinite deformation are studied in Updated Lagrangian rate forms.It is proved that theconvexity of the variational functionals are closely related to a so-called gap function,which plays an important role in nonlinear variational problems. |
