*CURE SHRINKAGE

Define the cure shrinkage coefficients for cure modeling capabilities.

This option is used to define the cure shrinkage coefficients for cure modeling capabilities. It must be used in conjunction with the CURE KINETICS option.

Optional parameters

DEPENDENCIES
Set this parameter equal to the number of field variables, in addition to temperature, on which the coefficients depend. If this parameter is omitted, it is assumed that the cure shrinkage coefficients are constant or depend only on temperature.
TYPE

Set TYPE=ISO (default) to define isotropic cure shrinkage.

Set TYPE=VOL to define volumetric cure shrinkage.

Set TYPE=ORTHO to define orthotropic cure shrinkage.

Set TYPE=ANISO to define anisotropic cure shrinkage.
