Four examples are presented in this document to demonstrate OptiStruct contact using ALM (Augmented Lagrange Multiplier) method in implicit nonlinear static analysis.
1) Rubber Ring: Compression of a ring made of a Hyperelastic material in excess of 100% strain, involving self-contact
2) Wedge: Large deformation of a plastic part resembling a wedge
3) Solid Rubber Tire Compression: Involves compression of solid rubber tire on a metal wheel
4) Rolling Fatigue Virtual Test: Virtual simulation of the rolling fatigue test using a simplified model
