CREATE A MAT_36E¶
Generates an LS-DYNA MAT_036 (*MAT_3-PARAMETER_BARLAT) keyword block for anisotropic elastic-plastic sheet materials. Supply material constants and per-direction hardening curves; the worker assembles the formatted keyword text ready for deck inclusion.
When to use¶
Classification: data.
Tagged: MAT_3-PARAMETER_BARLAT, anisotropic, barlat, hardening, keyword, ls-dyna, mat_036, mat_36.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Material Name | material_name | scalar | — | Alphanumeric label written into the MAT_36 keyword header (e.g. ‘DP600_rolled’); leave blank to omit a name field. | |
| Material ID | material_i_d | scalar | — | Integer material ID referenced by element sections in the deck; must be unique within the model — leave blank to assign automatically. | |
| Density | density | scalar | — | Mass density of the material in model-consistent units (e.g. kg/mm³ or t/mm³); required for any dynamic analysis. | |
| Elastic Modulus | elastic_modulus | scalar | — | Young’s modulus in model-consistent pressure units (e.g. MPa); governs elastic stiffness before yielding. | |
| Poissons Ratio | poissons_ratio | scalar | — | Poisson’s ratio (dimensionless, 0–0.5); controls lateral strain coupling in the elastic regime — typical steel value is 0.3. | |
| Starting Curve Id | starting_curve_id | scalar | 1 | Integer ID assigned to the first load-curve generated for this material; subsequent curves are numbered consecutively from this base — default is 1. | |
| Number Of Dig Points | numberof_dig_points | scalar | 200 | Number of discrete points used to digitise each hardening curve when writing the *DEFINE_CURVE entries; default 200 is sufficient for most applications; reduce for smaller deck size. | |
| R00 Hardening Curve | r00hardening_curve | vector | — | True stress vs. true plastic strain hardening curve measured (or fitted) in the rolling direction (0°); provided as an XY vector or curve object. | |
