COMPUTE ENG STRAIN TO EFFECTIVE PLASTIC STRAIN¶
Converts an engineering stress-strain curve to effective plastic strain by subtracting the elastic component using the provided elastic modulus. Use this worker when preparing true/plastic strain data for material card calibration (e.g., MAT_24) from raw coupon test results.
When to use¶
Classification: process.
Tagged: MAT_24, coupon, curve_transform, elastic_modulus, eng_strain, material_calibration, plastic_strain, stress_strain.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Eng Stress Strain Curve | eng_stress_strain_curve | vector | — | Engineering stress-strain curve (2-column vector: strain vs. stress, typically in GPa or MPa); the raw coupon test curve from which plastic strain will be derived. | |
| Elastic Modulus | elastic_modulus | scalar | 210 | Young’s modulus of the material in GPa used to compute the elastic strain offset; defaults to 210 GPa (steel) — change for aluminium or other alloys. | |
| Strain | strain | scalar | — | Optional scalar strain value at which to evaluate or offset the plastic strain calculation; leave blank to process the full curve. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_eng_strain_to_plastic_output_1 | curve_eng_strain_to_plastic_output_1 | scalar | Effective plastic strain scalar (or curve) computed by subtracting the elastic strain component (σ/E) from the engineering strain at each point. |
