EFFECTIVE TO TRUE OR ENG (SINGLE KNOB, BATCH)¶
Batch counterpart of curve_eff_to_true_or_eng — applies the same Output Type uniformly to every input curve. Useful when reconstructing many materials at once via a CurveGroup.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Effective Stress Vs Strain Curves | effective_stress_strain_curves | vector | — | Collection (CurveGroup) of effective stress-strain curves to be converted; each curve is a 2-column (strain, stress) vector — supply one or more curves for batch processing. | |
| Modulus | modulus | scalar | 210 | Young’s modulus used to separate elastic and plastic strain during conversion (GPa or consistent stress units); defaults to 210 (steel-like value). | |
| Yield Offset | yield_offset | scalar | 0 | Yield-offset strain value applied when locating the yield point (dimensionless); defaults to 0 (no offset, i.e. 0.2% offset not applied unless specified). | |
| Output Type | output_type | select | true | Target stress-strain convention for all output curves: ‘true’ converts to true (Cauchy) stress-strain, ‘eng’ converts back to engineering stress-strain; defaults to ‘true’. | |
| Poisson’s Ratio | poisson’s_ratio | scalar | 0 | Poisson’s ratio used in the lateral-strain correction during conversion (dimensionless, 0–0.5); defaults to 0 (no lateral correction). | |
| Tension/Compression Flag | tension/compression_flag | select | tension | Indicates whether the input curves represent tensile (‘tension’) or compressive (‘compression’) test data, which affects sign conventions in the transformation; defaults to ‘tension’. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_eff_to_true_or_eng_output_1 | curves_eff_to_true_or_eng_output_1 | vector | Batch of converted stress-strain curves (CurveGroup), each transformed to the requested Output Type (true or engineering convention), in the same order as the input curves. |
