ProductsAbaqus/Explicit Elements testedC3D8R Features testedUser subroutine to define hardening for the following plasticity models: Mises plasticity, Hill plasticity, combined hardening, and porous metal plasticity. Problem descriptionThis test verifies that the user-defined yield stress and its derivatives in user subroutine VUHARD are transferred properly to the solution process. The finite element model consists of multiple disconnected cubes made of a single C3D8R element. Each element is associated with one of the plasticity models listed above, and in each case a user-defined hardening is implemented. For comparison purposes, a duplicate set of elements with equivalent plasticity and isotropic hardening definitions is included to provide a reference solution. Results and discussionIn each case the results in the testing element match the solution in the reference element. Input files
