*MERGE INDIVIDUALLY OPTIMIZED DAMAGE CURVES*
============================================

Merges individually optimized GISSMO damage curves (one per triaxiality regime) into a single, ordered damage-curve set ready for LS-DYNA keyword authoring. Per-regime representative values (avg/min/max) are selected for shear, uniaxial, notch, and biaxial specimens, and triaxiality points outside the failure locus are capped with a configurable non-failure sentinel. Use this worker as the final assembly step after per-specimen GISSMO calibration.

When to use
-----------

Classification: **process**.

Tagged: ``biaxial``, ``damage_curve``, ``failure_locus``, ``gissmo``, ``mat_24``, ``material_calibration``, ``merge``, ``notch``.

     - 
     - Collection of individually optimized GISSMO damage curves (one curve per triaxiality specimen type), supplied in ascending order of triaxiality; accepts multiple curve objects.
   * - Non Failure Value
     - non_failure_value
     - scalar
     - 10
     - 
     - Sentinel damage value (dimensionless) assigned to triaxiality points outside the failure locus; defaults to 10, which safely flags non-failure regions in LS-DYNA GISSMO cards.
   * - Shear Value Type
     - shear_value_type
     - text
     - avg
     - 
     - Statistic used to represent the shear damage curve when multiple replicates are available; choose 'avg' (default), 'min', or 'max'.
   * - Uniaxial Value Type
     - uniaixal_value_type
     - text
     - avg
     - 
     - Statistic used to represent the uniaxial damage curve when multiple replicates are available; choose 'avg' (default), 'min', or 'max'.

     - avg
     - 
     - Statistic used to represent the notch damage curve when multiple replicates are available; choose 'avg' (default), 'min', or 'max'.
