You can create a material model to describe a low-density, highly
compressible elastomeric foam with significant rate-sensitive behavior (such as
polyurethane foam).
Abaqus
calculates material parameters from test data that you enter in the
Test Data Editor. You must provide uniaxial test data for
both tension and compression. Your test data must specify the uniaxial
stress-strain curve for different strain-rate values.
