*CONVERT BIAXIAL ENG STRESS-STRAIN TO COMPRESSION ENG STRESS-STRAIN*
====================================================================

Converts a biaxial engineering stress-strain curve (from equibiaxial tension tests on elastomeric materials) into its equivalent compression engineering stress-strain curve. Use this worker when preparing multi-mode material calibration inputs for hyperelastic or rubber-like material models that require compression data derived from biaxial test results.
