LS-DYNA GISSMO Failure Model

Test ID



Rate dependent tensile data are generated at 5 strain rates from .01 -100/s. Two grooved tensile tests; two shear tests at 0 and 45 deg angles using digital image correlation (DIC). An Erichssen cupping test, for biaxial failure; density. Price includes specimen preparation, testing and GISSMO model data processing by an external consultant.

Included Tests

1x D-010 Solid Density
2x M-204 Tensile Stress-Strain, Strength, and Modulus
1x Z-999 Custom Test
3x M-232 High Speed Tensile Stress-Strain
3x M-204V True Stress Strain Measurements Using 3D DIC


The model can be augmented with additional tests to characterize the degradation in performance due to the punching of the sheet metal. The maximum strain rate can also be extended to 1000/s.


: 5 thin sheets or film



The GISSMO damage model available in *MAT_ADD_EROSION of LS-DYNA provides the ability to add material damage and failure to constitutive material models such as MAT_024, which do not contain this ability. The model is a phenomenological formulation that allows for an incremental description of damage accumulation, including softening and failure for a variety of metallic materials.
