| Abstract: | In this paper,the incremental theory of an elastoplastic problem is trans- formed to a variational inequality.The existence and uniqueness of the variational inequality are proved for the materials in which the Drucker postulate is satisfied.And the convergence of the finite element solutions is also discussed. |
