Pressure over closure function for Polyurethane or (nearly) incompressible materials in general

Hi,

Is anyone aware of a pressure-overcosure function for (nearly) incompressible materials.

 I am aware of functions for PE and articular cartilage but they do not work with v=0.5.   I have been trying to find similar functions for elastomers, but can't seem to find anything.

 I am grateful for any input.

Modeling polyurethane

constitutive models

I've started to look into the modeling of polyurethane.  So far I'v found one paper that specifically looks into how to model the mechanical behavior of PU. It describes a possible constitutive model for PU:

Stress-strain behavior of thermoplastic polyurethanes, Qi,H.J.; Boyce, M.C., Mech. Mater. 2005, 37, 8, 817-839

Does someone know of any other resources on the modeling of PU?  Thanks, Andreas
