LS-DYNA Hyperelastic (MAT_027)
Tests are performed to provide data for hyperelastic modeling. Tests include uniaxial tensile and compression data. The uniaxial data is fit to either a Mooney-Rivlin or Ogden model. Data is presented in the MAT-027 card format for easy implementation into LS-DYNA. Unless otherwise requested, the material is precycled at 100% strain to account for Mullins effects.

If simulations of initial deformations are desired, please specify "no precycling".

This TestPak is used to model highly elastic materials that show incompressibility in their application. Materials such as rubbers are typically tested in this fashion.
