Case Specification

The problem consists in two cylinders with hyperelastic behaviour. We impose a vertical displacement in the upper cylinder. The two cylinders become into contact and deal with self-contact in the inner ring of the upper cylinder.

Materials:

• Upper Cylinder. E=10000 ν=0.3
• Lower Cylinder. E=100000 ν=0.3
