COMPUTE THE YIELD OFFSET LINE USING THE MODULUS, AND OFFSET FACTOR¶
Constructs the classic 0.2 % (or user-defined) yield-offset line by shifting the elastic modulus line horizontally by the specified strain offset. Use this worker to overlay the offset line on a stress–strain curve when identifying the proof/yield stress graphically.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| offset | offset | float | 0.002 | Horizontal strain offset applied to the elastic modulus line (dimensionless strain, e.g. 0.002 for the standard 0.2 % offset rule); defaults to 0.002 if left unset. | |
| modulus | modulus | float | 1 | Slope of the offset line, i.e. the elastic (Young’s) modulus in consistent stress/strain units (e.g. GPa or MPa); defaults to 1 if left unset — always override with the actual material modulus. | |
| max_x | max_x | float | 1 | Maximum strain (x-axis) value at which the offset line is truncated; defaults to 1e20 (effectively unlimited) — set this to the upper strain limit of the parent stress–strain curve to keep the plot tidy. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_yieldoffsetline_output_1 | curve_yieldoffsetline_output_1 | vector | Two-column (strain, stress) vector representing the yield-offset line, ready to overlay on a stress–strain plot for graphical yield-point determination. |
