A General Solution for Implicit Time Stepping Scheme in Rate-dependant Plasticity

In this paper derivation of the second differentiation of a general yield surface by 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-dependant plasticity.It is shown that implementing fully implicit time stepping scheme in rate-dependant plasticity predicts more accurate experimental results than other schemes
