CONVERT A FORCE-DEFLECTION CURVE TO A TRUE STRESS VS STRAIN CURVE BASED¶
Converts a force-deflection (force-displacement) curve into a true stress vs. true strain curve using the specimen’s gauge length and initial cross-sectional area. Use this worker during material characterization workflows to transform raw coupon test data into the true stress-strain representation required for material card calibration.
When to use¶
Classification: process.
Tagged: coupon, cross-section, force-deflection, gauge-length, material-testing, stress-strain-conversion, true-strain, true-stress.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Force Deflection Curve | forcedeflectioncurve | vector | — | Input force-displacement curve (X: displacement in length units, Y: force in force units) obtained from a physical coupon test; leave unconnected only if the curve is supplied via another mechanism. | |
| Length | length | float | 1 | Gauge length of the specimen in consistent length units (e.g. mm); used to compute engineering strain as displacement / gauge length — defaults to 1.0 if the curve is already in strain units. | |
| Area | area | float | 1 | Initial cross-sectional area of the specimen at the gauge section in consistent area units (e.g. mm²); used to compute engineering stress as force / area — defaults to 1.0 if the curve is already in stress units. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| True Stress vs Strain | true_stress_vs_strain | vector | Resulting true stress vs. true strain curve (X: true strain dimensionless, Y: true stress in the same pressure units as force/area), ready for use in material card calibration or GISSMO fitting. |
