COMPUTE BILINEAR STATS¶
Fits a bilinear approximation to an input curve and returns key statistical parameters describing the two-segment linear fit (e.g., breakpoint location, slopes, intercepts). Use this worker when you need a compact, interpretable bilinear characterisation of a stress-strain or force-displacement curve.
When to use¶
Classification: process.
Tagged: bilinear, breakpoint, curve_stats, force-displacement, slope, stress-strain, transformations, two-segment.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input XY curve (e.g., force-displacement or stress-strain) supplied as a two-column vector; the worker fits the bilinear model to this data. Optional — if omitted, the worker returns empty/null outputs. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_bilinear_stats_output_1 | curve_bilinear_stats_output_1 | keyvalue | Key-value map of bilinear fit statistics, typically including breakpoint coordinates (x_break, y_break), pre- and post-break slopes, and intercepts for each linear segment. |
