VARIABLE DESCRIPTION

FLDID   FLD identification, must be unique 

LCID   Load curve ID which defines the forming limit curve (FLC).

Minor strains are defined as abscissa values and major strains are defined as ordinate values. In Define curve, the data in the left-most column are Minor strain values, and data in the right-most column are major strain values. Please refer to *DEFINE_CURVE

FLD0(E-S)   The lowest point of Minor engineering strain on FLC curve.

FLD0(T-S)   The lowest point of Minor true strain on FLC curve.

N           Work-hardening exponent

T           Thickness

R           Plastic anisotropy ratio
