Hi, all
I have a question about FE formulation for a finite plastic deformation.
I'm a new on the ABAQUS, but how the ABAQUS deals with the plastic deformation
to solve the FE eqation? I think the software use the principle of virtual work and
I'm wondering how the software modify the virtual work term to take the plastic deformation into account (because of dissipation energy)
(Obviously, the formulation must be different with elastic model)
I appreciate your reply.
