"Optional title"
did, erode, noic
$W_{0}$, $W_{45}$, $W_{90}$

Parameter definition

VariableDescription
did Unique damage identification number
erode Element erosion flag
options:
0 $\rightarrow$ failed element is not eroded
1 $\rightarrow$ failed element is eroded
2 $\rightarrow$ node splitting at failure (crack plane orthogonal to max principal strain)
3 $\rightarrow$ node splitting at failure (crack plane orthogonal max principal stress)
noic Flag to turn off cracking along interface between different materials
options:
0 $\rightarrow$ material interface cracks are allowed
1 $\rightarrow$ material interface cracks are not allowed
$W_{0}$ Damage parameter for the rolling/extrusion direction
$W_{45}$ Damage parameter for the 45 degree direction
$W_{90}$ Damage parameter for the transverse direction

Description

This is an anisotropic Cockcroft-Latham like failure criterion. The material will fail once the damage parameter, $D$, has evolved from 0 to 1.

The initial material orientation is defined using either INITIAL_MATERIAL_DIRECTION, INITIAL_MATERIAL_DIRECTION_VECTOR or INITIAL_MATERIAL_DIRECTION_WRAP.
