Based upon the rate tangent modulus for a viscoplastic material, a semi-implicit finite element code is developed for isotropic viscoplastic materials undergoing two dimensional plane strain deformations.
Dynamic and quasi-static solutions for each of hardening and softening materials are obtained from the finite element code. The quasi-static solution is compared with the dynamic solution for softening materials, and particularly the effect of inertia upon development of the shear band, originating from internal material inhomogeneity, is investigated.
