LS-DYNA Simplified Rubber with Rate Dependency (MAT_181)
Test ID
G-784
Description
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 |
Options
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.
Samples
: 6 hyperelastic test specimens
[details]Application
The LS-DYNA MAT_181 model applies to hyperelastic materials in which rate effects are considered.
