SCALE Y VALUES¶
Converts a true stress–strain curve to an effective (plastic) stress–strain curve by subtracting the elastic strain component using the supplied Young’s modulus. Use this worker when preparing material input curves for LS-DYNA MAT_24 or similar elasto-plastic material cards that require effective plastic strain on the X-axis.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| True Stress Vs Strain Curve | base_curve | vector | — | True stress vs. total strain curve (vector of [strain, stress] pairs, stress in MPa); this is the raw experimental or processed curve before elastic-strain removal. | |
| Modulus | modulus | text | 210 | Young’s modulus in GPa used to subtract the elastic strain component (default 210 GPa for steel); override for non-ferrous materials. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Effective Stress vs Strain Curve | curve_scale_up_output_1 | vector | Effective (plastic) stress vs. plastic strain curve produced by removing the elastic strain (σ/E) from each total-strain value; ready for direct use in elasto-plastic material definitions such as LS-DYNA MAT_24. |
