CONVERTS VOLUMETRIC TRUE STRESSES TO ENG STRESS¶
Converts volumetric true stress curves to engineering stress by combining the volumetric stress with transversal and thickness strain curves. Use this worker when material test data is available in volumetric/true-stress form and engineering stress is required for downstream curve fitting or material card authoring.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Volumetric Stress | curve_input | vector | — | Volumetric true stress curve(s) (stress vs. strain, dimensionless or MPa on Y-axis); accepts multiple curves — leave empty only if no volumetric stress data is available. | |
| Transversal Strain | e2curve | vector | — | Transversal (width) true strain curve paired point-for-point with the volumetric stress curve; required for accurate cross-section correction — omit only if transversal strain is unavailable. | |
| Thickness Strain | e3curve | vector | — | Thickness true strain curve paired point-for-point with the volumetric stress curve; required for through-thickness area correction — omit only if thickness strain is unavailable. | |
| Option to use either X value or by point index for interpolation | use_x_value | text | yes | Interpolation mode: ‘Yes’ syncs e2/e3 curves to the volumetric stress curve using matching X (strain) values; ‘By Index’ aligns curves by point index — default ‘Yes’ is preferred when all curves share the same X axis. | |
| X is True Strain | x_is_true_strain | text | no | Set to ‘Yes’ when the X-axis of the input curves is already true strain; set to ‘No’ (default) when the X-axis is engineering strain, triggering an internal conversion before processing. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Eng. Stress | curves_vts_output | vector | Resulting engineering stress curve(s) (MPa vs. engineering strain) converted from the input volumetric true stress data, ready for use in material calibration or FE deck authoring. |
