LS-DYNA Simplified Rubber with Rate Dependency (MAT_181)
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.

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.
