TRUE TO ENG STRAIN¶
Converts a true strain vs. time curve to engineering strain using the standard relationship ε_eng = exp(ε_true) − 1. Use this worker when material test data is recorded in true strain and a downstream process (e.g., MAT_24 card authoring) requires engineering strain.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| True Strain Vs Time Curve | truestrainvstimecurves | vector | — | True strain vs. time curve (dimensionless strain on Y-axis, time in seconds on X-axis) obtained from a material coupon test; leave unconnected if no conversion is needed. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_truetoengstrain_output_1 | curve_truetoengstrain_output_1 | vector | Engineering strain vs. time curve (dimensionless) derived from the input true strain curve via ε_eng = exp(ε_true) − 1; shares the same time axis as the input. |
