TRUE TO ENG STRAIN

Converts a true strain vs. time curve to engineering strain using the standard relationship ε_eng = exp(ε_true) − 1. Use this worker when material test data is recorded in true strain and a downstream process (e.g., MAT_24 card authoring) requires engineering strain.

When to use

Classification: process.

Tagged: curve_transform, engineering_strain, material_testing, strain_conversion, true_strain.

Inputs

Label ID Type Default Required Description
True Strain Vs Time Curve truestrainvstimecurves vector   True strain vs. time curve (dimensionless strain on Y-axis, time in seconds on X-axis) obtained from a material coupon test; leave unconnected if no conversion is needed.

Outputs

Label ID Type Description
curve_truetoengstrain_output_1 curve_truetoengstrain_output_1 vector Engineering strain vs. time curve (dimensionless) derived from the input true strain curve via ε_eng = exp(ε_true) − 1; shares the same time axis as the input.
