SCALE BASE CURVE TO STRAIN RATES¶
Scales a quasi-static base stress-strain curve to multiple strain rates by referencing a set of strain-rate curves. Use this worker when building rate-dependent material cards (e.g., MAT_24) that require a family of scaled curves across different strain-rate levels.
When to use¶
Classification: process.
Tagged: curve_scaling, mat_24, material_curves, quasi_static, rate_dependent, strain_rate.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve In | curve_in | vector | — | The base quasi-static stress-strain curve (vector of X-Y pairs, stress in MPa vs. engineering or true strain) that will be scaled to each target strain rate. | |
| Ref Strain Rate Curves Curves | ref_strain_rate_curves_curves | vector | — | Collection of reference strain-rate curves (multiple vectors) that define the scaling ratios at each strain-rate level; each curve should share the same strain axis as the base curve. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_scale_to_strain_rates_output_1 | curves_scale_to_strain_rates_output_1 | vector | Family of scaled stress-strain curves (one per reference strain rate), suitable for direct use as rate-dependent load curves in an LS-DYNA MAT_24 material card. |
