MSC.NASTRAN Hyperelastic Incompressible Model (MATHP)G-810

Description

This TestPak includes tensile stress-strain curves, compressive stress-strain curves, a planar tension test, and solid density to model deviatoric hyperelastic behavior. Data is fit to a Mooney-Rivlin model or the appropriate hyperelastic model. This TestPak does not account for volumetric effects.

Included Tests

1x	D-010	Solid Density
1x	M-205	Tensile Properties of Elastomers
1x	M-211	Lubricated Compressive Stress-Strain (Biaxial Tension)
1x	M-220	Planar Tension (Shear)

Options

For thin sheet materials, a biaxial tension test [M-218] may need to be performed instead of the compressive experiment.

Samples

: 6 hyperelastic test specimens

Application

This TestPak is used to model a material exhibiting an elastic response up to large strains. It describes approximately incompressible hyperelastic behavior. Materials such as rubbers and elastomers are approximated well using this model.
