Hyperelastic models are used extensively in the
finite element analysis of rubber and elastomers. These models need
to be able to describe elastomeric behavior at large deformations and
under different modes of deformation. In order to accomplish this daunting
task, material models have been presented that can mathematically describe
this behavior. There are several in common use today, notably, the Mooney-Rivlin,
Ogden and Arruda Boyce.
