摘要
在有限变形条件下,基于刚-粘塑性本构方程,提出了计算塑性应变增量的隐式时间积分方案,与传统的显式算法对比,此方案具有明显的优点,适用于有限变形大增量步的有限元计算,其数值精度令人满意。
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.
