CONVERTS VOLUMETRIC TRUE STRESS TO ENG STRESS¶
Converts a volumetric true stress curve to engineering stress by incorporating transversal and thickness strain curves. Use this worker when material test data is available in volumetric true-stress form and engineering stress–strain representation is required for downstream calibration or characterization workflows.
When to use¶
Classification: process.
Tagged: curve_transform, engineering_stress, material, strain, stress_conversion, true_stress, volumetric.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Choose The Curve | curve_input | vector | — | Volumetric true stress curve (X: strain or index, Y: true stress in consistent units, e.g. MPa) to be converted to engineering stress. | |
| Transversal Strain | e2curve | vector | — | Transversal strain curve (E2) measured during the test; must share the same X-axis domain as curve_input for interpolation to work correctly. | |
| Thickness Strain | e3curve | vector | — | Thickness strain curve (E3) measured during the test; must share the same X-axis domain as curve_input for proper volumetric correction. | |
| Option to use either X value or by point index for interpolation | use_x_value | text | yes | Controls interpolation alignment: ‘yes’ (default) matches curves by their X values; set to ‘no’ (By Index) to align E2/E3 curves point-by-point with curve_input regardless of X. | |
| X is True Strain | x_is_true_strain | text | no | Indicates whether the X-axis of curve_input is true strain (‘yes’) or engineering strain (‘no’, default); affects the strain-to-stretch conversion used in the stress transformation. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Eng. Stress | curve_vts_output | vector | Resulting engineering stress curve (X: strain matching the input convention, Y: engineering stress in the same units as curve_input) after volumetric true-stress conversion. |
