COMPUTE THE EQUIVALENT STRAIN PLOT¶
Computes the equivalent strain curve from two principal strain components (E1 and E2). Given E1 and E2 strain time-history vectors, it applies the equivalent-strain formula and returns the resulting combined strain curve. Use this worker when you need to derive a scalar equivalent strain signal from biaxial principal strain data.
When to use¶
Classification: process.
Tagged: biaxial, curves, e1, e2, equivalent_strain, principal_strain, strain_transformation.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| E1 Strain | e1strain | vector | — | First principal strain time-history (E1) as a curve vector or CurveGroup; if a CurveGroup is supplied, only the first curve is used. Optional — leave unset if E1 data is not available. | |
| E2 Strain | e2strain | vector | — | Second principal strain time-history (E2) as a curve vector or CurveGroup; if a CurveGroup is supplied, only the first curve is used. Optional — leave unset if E2 data is not available. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_equivalent_strain_output_1 | curves_equivalent_strain_output_1 | vector | Computed equivalent strain curve (dimensionless strain vs. time or index), derived from E1 and E2 using the equivalent-strain combination formula at the configured number of interpolation digits (default 100). |
