LS-DYNA Hyperviscoelastic Rubber (MAT_077)

Test ID



Testing and model fitting areperformed to generate data for hyperviscoelastic rubber material models. Hyperelastic material properties are generated as per [G-780] with either a Mooney-Rivlin or Ogden model. Additionally, stress relaxation measurements are performed and a six parameter Prony series is fit to the master curve viscoelastic data. Both models are used to create a MAT_077 model for LS-DYNA (either MAT_077_H or MAT_077_O depending on what hyperelastic model is used in fitting).

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-611 Stress Relaxation/Creep Compliance by Time Sweeps


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


: 6 hyperelastic test specimens



This model is useful for hyperelastic materials that show rate effects. This can be used to simulate impact loading or creep situations depending on how the stress-relaxation measurements are made.
