CONVERT A FORCE-DEFLECTION CURVE TO A ENGINEERING STRESS VS STRAIN CURVE BASED¶
Converts a force-deflection (force-displacement) curve into an engineering stress vs. strain curve using the specimen’s gauge-section geometry. Supports rectangular and circular cross-sections; stress is computed as force divided by initial cross-sectional area and strain as deflection divided by gauge length.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Force Deflection Curve | forcedeflectioncurve | vector | — | Input force-displacement curve (X = displacement/deflection, Y = force) measured from the coupon test; must be provided as a two-column vector before any cross-section conversion is applied. | |
| Section Type | sectiontype | scalar | rectangle | Cross-section shape of the specimen at the gauge region — ‘rectangle’ (default) for flat/sheet specimens or ‘circular’ for round-bar specimens; determines how the cross-sectional area is calculated. | |
| Length | length | float | 1.0 | Gauge length of the specimen (scalar, same length units as the deflection axis of the input curve; default 1.0); used as the denominator when computing engineering strain. | |
| Width Or Radius | widthorradius | float | 1.0 | Width of the specimen (for rectangular sections) or radius (for circular sections) at the gauge, in the same length units as gauge length (default 1.0); used to compute the initial cross-sectional area. | |
| Thickness | thickness | float | 1.0 | Thickness of the specimen at the gauge, in the same length units as gauge length (default 1.0); used only for rectangular cross-sections to complete the area calculation (width × thickness). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_forcedeflectiontoengstressstrain_section_output_1 | curve_forcedeflectiontoengstressstrain_section_output_1 | vector | Resulting engineering stress vs. engineering strain curve (X = engineering strain [dimensionless], Y = engineering stress [force/area units consistent with inputs]), ready for downstream material characterization or calibration workers. |
