Algorithm for viscoplastic FEA analysis
Algorithm for viscoplastic FEA analysis
(OP)
I am trying to solve a FEA problem with viscoplastic strains using the fully explicit method described in Zienkiewicz, Vol 2, Chap. 7. It is basically a Euler method of solving the nonlinear equations, and I am having convergence problems. I cannot use the implicit method because the Jacobian matrix cannot be determined with the material model I have. Does anybody know of a better algorithm to solve such problems? Thanks.
