Products: Abaqus/Standard Abaqus/Explicit
Modifications to the contact pressure-overclosure relationship are tested for a number of cases.
This set of tests verifies the softened contact option. All the tests are for axisymmetric, large-displacement, static analyses with finite sliding. The model in each test consists of a die pressing down on a rubber cylinder. The die is modeled either as a rigid surface or as a deformable body with mild steel properties. CAX4 elements are used in the Abaqus/Standard analyses, and CAX4R elements are used in the Abaqus/Explicit analyses. The blank is modeled as an incompressible Mooney-Rivlin material with CAX4H elements in Abaqus/Standard and CAX4R elements in Abaqus/Explicit. The bottom surface of the blank is constrained against vertical motion.
Each analysis has one step, in which a vertical prescribed displacement is applied to the die.
The analysis results indicate that the die penetrates the blank according to the prescribed pressure-overclosure relationship.
