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 by dividing force by the original cross-sectional area and displacement by the original gage length. Use this worker when processing uniaxial coupon test data to produce the standard engineering stress-strain representation needed for material characterization workflows.
When to use¶
Classification: process.
Tagged: coupon, curve-conversion, engineering-stress-strain, force-deflection, material-testing, uniaxial.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Force Deflection Curve | forcedeflectioncurve | vector | — | Input force-displacement curve (X = displacement, Y = force) obtained from a physical coupon test; units must be consistent with the length and area inputs (e.g., mm and N, or in and lbf). | |
| Length | length | float | 1 | Original gage length of the specimen used to compute engineering strain (strain = deflection / length); must use the same length unit as the displacement axis of the input curve — defaults to 1 (dimensionless pass-through). | |
| Area | area | float | 1 | Original cross-sectional area at the gage section used to compute engineering stress (stress = force / area); must use units consistent with force and desired stress units (e.g., mm² for MPa when force is in N) — defaults to 1 (dimensionless pass-through). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_forcedeflectiontoengstressstrain_output_1 | curve_forcedeflectiontoengstressstrain_output_1 | vector | Resulting engineering stress vs. strain curve (X = engineering strain [dimensionless], Y = engineering stress [force/area units]), ready for material characterization or calibration workflows. |
