Abstract

Abstract: In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependent plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependent plasticity predicts experimental results more accurate than the other schemes.
