Card 3
Curve ID defining the Flow Limit Diagram.
Minor strains in percent are defined as abcissa values
Major strains in percent are defined as ordinate values
The flow limit diagram is shown in Figure 3.17. In
defining the curve, list pairs of minor and major
strains starting with the left most point and ending
with right most point.

modulus are ignored with this option.

See material model 37 for the theoretical basis. The first history variable is the
maximum strain ratio defined by:
ε major workpiece
ε major fld
corresponding to ε minor workpiece .
