ERSATZ HARDENING CURVE GENERATOR¶
Generates ERSATZ hardening curves from a material dataset by reading engineering yield stress, ultimate stress, and necking strain columns. Use this worker to rapidly produce piecewise-linear true stress–plastic strain hardening definitions suitable for ERSATZ/MAT_24 material cards.
When to use¶
Classification: process.
Tagged: curve_generation, ersatz, hardening_curve, mat_24, material_curve, necking_strain, plastic_strain, true_stress.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Choose Dataset | dataset_1 | dataset | — | Input material dataset (tabular) containing at minimum columns for engineering yield stress, ultimate stress, and necking strain; each row typically represents one material lot or coupon test. | |
| Eng Yield Stress Column | eng_yield_stress_column | scalar | Yield Stress | Name of the dataset column holding engineering yield stress values (e.g. in MPa); defaults to ‘Yield Stress’ — change only if your dataset uses a different column header. | |
| Eng Ultimate Stress Column | eng_ultimate_stress_column | scalar | Ultimate Stress | Name of the dataset column holding engineering ultimate (tensile) stress values (e.g. in MPa); defaults to ‘Ultimate Stress’ — change only if your dataset uses a different column header. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_get_ersatz_hardening_from_dataset_output_1 | curves_get_ersatz_hardening_from_dataset_output_1 | vector | Vector of ERSATZ hardening curves (true stress vs. plastic strain) derived from the dataset rows, ready for direct use in MAT_24 / ERSATZ material card authoring. |
