*MEAN FIELD DAMAGE

Define the impact of microlevel damage on the behavior of the composite material at the macro level.

This option is used to define the impact of microlevel damage on the behavior of the composite material at the macro level.

Required parameters

DEGRADATION

Set DEGRADATION=MAXIMUM to specify that the overall damage variable of the composite is determined using the maximum of the overall damage variable in all the constituents.

Set DEGRADATION=MULTIPLICATIVE to specify that the overall damage variable of each constituent contributes to the overall damage variable of the composite in a multiplicative sense.

Set DEGRADATION=USER to specify a user-defined overall damage behavior for the composite in a user subroutine. User-defined damage is supported only in Abaqus/Standard.

Optional parameters

PROPERTIES

This parameter can be used only if DEGRADATION=USER.

Set this parameter equal to the number of property values required as data in user subroutine UDAMAGEMF. The default is 0.

Data line for a user-defined overall damage variable (DEGRADATION=USER)

First line

  1. Material properties, eight per line.

Repeat this data line as often as necessary to define material properties.

No data lines are needed if the PROPERTIES parameter is omitted or set to 0.
