摘要：
In the cases of implicit or semi-implicit time integrations applied to the finite element solution of elasto-viscoplastic and creep problems, matrix inversion has to be performed to compute the stress increment. The present paper discusses the direct evaluation of the inverse of this constitutive tangent matrix for Perzyna's viscoplastic theory using Mises' yield condition.
