| Abstract: | A kind of implicit time integration scheme for calculating plastic strain increments in connection with rigid-viscoplastic constitutive is proposed. Advantages of the scheme are obvious,comparing with traditional explicit algorithms. The present scheme is specifically suitable to finite element computations of finite deformation with large incremental steps, showing remarkable numerical accuracy. |
