LS-DYNA Simplified Rubber with Rate Dependency (MAT_181)

Test ID



The LS-DYNA model includes five tensile and compression tests to generate rate dependent uniaxial data. Unless otherwise requested, the material is precycled at 100% strain to account for Mullins effects. Data are fit to a MAT_181 material model.

Included Tests

1x D-010 Solid Density
3x M-205 Tensile Properties of Elastomers
2x M-232 High Speed Tensile Stress-Strain
3x M-211 Lubricated Compressive Stress-Strain (Biaxial Tension)
2x M-231 High Speed Compressibility of Foams and Elastomers


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

An option for bulk modulus test [M-014] can be added to the TestPak for an additional cost.


: 6 hyperelastic test specimens



The LS-DYNA MAT_181 model applies to hyperelastic materials in which rate effects are considered.
