Field | Contents | SI Unit Example |
---|---|---|
DMGINIID | Damage initiation
identification number. No default (Integer > 0) |
|
CRI | Damage initiation criteria.
No default (Real) |
|
LODE | Valid only for
CRI=DUCTILE. Flag to activate load parameter dependence for ductile damage initiation. Default = blank |
|
FLAT | Valid only for
CRI=DUCTILE. Specifies the handling method for y-values outside the specified range of x-values.
|
|
Y_#, X#_i, X#_j, X#_k | The maximum value of
strain or stress/traction depending on damage initiation
type. No default (Real > 0.0) |

MAXE/QUADE criteria for MAXS/QUADS criteria |
Comments
- The material identification number should be unique for all MAT1, MAT2, MAT3, MAT8, MAT9, MGASK, MCOHE, MCOHED, DMGINI, and DMGEVO entries.
- Analysis support information for
the criteria are:
Analysis Types Criterion Nonlinear Static Analysis, Nonlinear Transient Analysis MAXE, MAXS, QUADE, QUADS Explicit Dynamic Analysis DUCTILE - When the DUCTILE
damage initiation criterion is used, the parameters are used:
