CHECKS FOR LOCALIZATION¶
Detects the onset of plastic localization (necking) in a stress-strain curve. Accepts either engineering or true stress-strain input and returns a boolean scalar indicating whether localization has occurred. Use this worker to quality-check coupon test curves before material calibration.
When to use¶
Classification: process.
Tagged: coupon, engineering_curve, localization, material_check, necking, stress_strain, true_curve.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Engineering Stress Strain Curve | curve_in | vector | — | Engineering or true stress-strain curve (vector of strain–stress pairs) to be checked for localization onset; leave unconnected to test with a null curve. | |
| Type of Curve | curve_type | scalar | eng | Specifies whether the input curve is engineering stress-strain (‘eng’) or true stress-strain (‘true’); defaults to ‘eng’ — change to ‘true’ only when a converted true-stress curve is supplied. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Has Localization | curve_has_output_1 | scalar | Boolean scalar (1 = localization detected, 0 = not detected) indicating whether the supplied stress-strain curve exhibits a necking / localization instability. |
