Hyperelastic Seal

Loads that depend on the deformation are often termed follower loads. The most common case is a pressure directed along the normal to a surface which deforms. In general, both the direction of the load and the area of the loaded surface will change. This model studies the force-deflection relation of a car door seal made from a soft rubber. The seal is compressed between a stationary plane surface and an indenting cylinder.

The model uses an hyperelastic material model together with formulations that can account for the very large deformations.
