CONVERT A FORCE-DEFLECTION CURVE TO A ENGINEERING STRESS VS STRAIN CURVE BASED¶
Converts an engineering stress-strain curve to a force-deflection curve (or vice versa) using specimen gauge geometry. Provide the cross-section type and dimensions to scale between stress/strain and force/deflection domains. Use this worker when preparing material coupon data for LS-DYNA material card input or for comparing test-machine outputs with stress-strain characterisation results.
When to use¶
Classification: process.
Tagged: circular, conversion, coupon, cross-section, curve, engineering-strain, engineering-stress, force-deflection.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Eng Stress Strain | eng_stress_strain | vector | — | Input engineering stress-strain curve (vector of stress vs. strain pairs) to be converted to force-deflection; leave empty if the conversion direction is reversed. | |
| Section Type | sectiontype | scalar | rectangle | Cross-section shape at the gauge region — ‘rectangle’ (requires width and thickness) or ‘circular’ (requires radius); defaults to ‘rectangle’. | |
| Length | length | float | 1.0 | Gauge length of the specimen in consistent model units (e.g. mm); used to convert strain to deflection — defaults to 1.0. | |
| Width Or Radius | widthorradius | float | 1.0 | Width of a rectangular cross-section or radius of a circular cross-section at the gauge, in consistent model units (e.g. mm) — defaults to 1.0. | |
| Thickness | thickness | float | 1.0 | Thickness of a rectangular cross-section at the gauge in consistent model units (e.g. mm); ignored for circular sections — defaults to 1.0. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_engstressstrain_forcedeflection_output_1 | curve_engstressstrain_forcedeflection_output_1 | vector | Resulting force-deflection curve (vector of force vs. displacement pairs) derived from the input engineering stress-strain curve and the supplied specimen geometry. |
