(Transversely Anisotropic with FLD) Material Type 39 Material Type 39 (Transversely Anisotropic Elastic-Plastic with FLD) Columns Quantity Format 1-10 Card 3 Young’s modulus E10.0 11-20 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. E10.0 1-10 Card 4 Poisson’s ratio E10.0 1-10 Card 5 Yield stress E10.0 1-10 Card 6 Hardening modulus, Et E10.0 1-10 Card 7 Anisotropic hardening parameter, R E10.0 1-10 Card 8 Load curve ID defining effective stress versus effective plastic strain. The yield stress and hardening modulus are ignored with this option. E10.0 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 . LS-DYNA Version 960 3.39.1m
