DMGINIID

Damage initiation identification number.

No default (Integer > 0)

CRI

Damage intiation criteria.

MAXE: Damage is initiated when the strain in any direction reaches the corresponding maximum value.
MAXS: Damage is initiated when the stress/traction in any direction reaches the corresponding maximum value.
QUADE: Damage is initiated based on quadratic form of strain.
QUADS: Damage initiated based on quadratic form of stress/traction.

No default (Real)

V1. V2, V3

The maximum value of strain or stress/traction depending on damage initiation type.

No default (Real > 0.0)

[a b s]

for MAXE/QUADE criteria

$\frac{N}{m^{2}}$ for MAXS/QUADS criteria

The material identification number should be unique for all MAT1, MAT2, MAT3, MAT8, MAT9, MGASK, MCOHE, MCOHED, DMGINI, and DMGEVO entries.
