LS-DYNA GISSMO Failure Model
Test ID
G-776
Description
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 and testing. No model fitting or calibration is performed
Included Tests
| 5x | M-204V 3D | True Stress Strain Measurements Using 3D DIC |
| 3x | M-232 | High Speed Tensile Stress-Strain |
| 2x | M-204 | Tensile Stress-Strain, Strength, and Modulus |
| 1x | D-010 | Solid Density |
| 1x | M-242 | Biaxial Force and Surface Strain by Punch Test |
| 1x | SP-105 | Specimen Machining Services |
Options
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.
Samples
: 5 thin sheets or film
[details]Application
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.
