COMPUTE THE TRUE STRAIN FROM ENG STRAIN¶
Converts engineering strain curves to true strain using the standard logarithmic transformation (ε_true = ln(1 + ε_eng)). Use this worker when preparing material test data for large-deformation FEA where true strain is required.
When to use¶
Classification: process.
Tagged: curve_transform, eng_to_true_strain, engineering_strain, logarithmic_strain, material_test, strain_conversion, true_strain.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves | curves | vector | — | One or more engineering strain curves (X-axis: engineering strain, dimensionless) to be converted; accepts multiple curves in batch — leave empty to pass curves dynamically from an upstream worker. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_eng_to_true_strain_output_1 | curve_eng_to_true_strain_output_1 | vector | Transformed curve(s) with X-axis values converted to true strain via ln(1 + ε_eng), preserving the original Y-axis data (e.g., stress) unchanged. |
