SCALE Y VALUES

Converts a true stress–strain curve to an effective (plastic) stress–strain curve by subtracting the elastic strain component using the supplied Young’s modulus. Use this worker when preparing material input curves for LS-DYNA MAT_24 or similar elasto-plastic material cards that require effective plastic strain on the X-axis.

When to use

Classification: process.

Tagged: ", 2, 4, A, M, T, _, a.

Inputs

Label ID Type Default Required Description
True Stress Vs Strain Curve base_curve vector   True stress vs. total strain curve (vector of [strain, stress] pairs, stress in MPa); this is the raw experimental or processed curve before elastic-strain removal.
Modulus modulus text 210   Young’s modulus in GPa used to subtract the elastic strain component (default 210 GPa for steel); override for non-ferrous materials.

Outputs

Label ID Type Description
Effective Stress vs Strain Curve curve_scale_up_output_1 vector Effective (plastic) stress vs. plastic strain curve produced by removing the elastic strain (σ/E) from each total-strain value; ready for direct use in elasto-plastic material definitions such as LS-DYNA MAT_24.
