COMPUTE THE TRUE STRAIN FROM ENG STRAIN¶
Converts an engineering strain curve to true strain using the standard relationship ε_true = ln(1 + ε_eng). Use this worker when preparing stress-strain data for material model calibration or any analysis requiring logarithmic (true) strain values.
When to use¶
Classification: process.
Tagged: curve_transform, engineering_strain, material_testing, strain_conversion, stress_strain, true_strain.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input engineering strain curve (X-axis: engineering strain [dimensionless], Y-axis: any paired quantity such as stress [MPa]); leave unconnected if no transformation is needed. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_eng_to_true_strain_output_1 | curve_eng_to_true_strain_output_1 | vector | Output curve with the X-axis values converted to true strain via ln(1 + ε_eng); Y-axis values are passed through unchanged. |
