*REGULARIZE BASED ON UNIAXIAL DATA*
===================================

Computes mesh-size-regularized failure curves for GISSMO-style material models by combining a uniaxial regularization (failure scale-factor vs. characteristic length), an instability curve, and a damage (triaxiality) curve. Use this worker to produce the element-size-corrected failure locus covering compression, shear, uniaxial, notch, and punch load states.

     - uniaxial_regularization
     - vector
     - —
     - 
     - Failure scale-factor as a function of characteristic element length (dimensionless scale-factor vs. mm); defines how the uniaxial failure strain is adjusted for mesh size — leave unconnected only if regularization is not required.
   * - Instability Curve
     - instability
     - vector
     - —
     - 
     - Instability onset curve derived from the hardening curve (equivalent plastic strain vs. stress triaxiality or similar); marks the onset of localisation for each stress state.
   * - Damage Curve
     - damage
     - vector
     - —
     - 
     - GISSMO damage (failure) curve expressed as equivalent plastic strain to failure vs. stress triaxiality; serves as the base failure locus before mesh-size correction.
