Required parameters
- TYPE
Set TYPE=MOTION to use either connector constitutive relative motions
(displacements/rotations) or plastic relative motions (displacement/rotations)
to specify damage evolution.
Set TYPE=ENERGY to use post-damage initiation dissipation energies to specify
damage evolution.
Optional parameters
- AFFECTED COMPONENTS
Include this parameter to identify on the data line the components of
relative motion that will be damaged.
If this parameter is omitted and the COMPONENT parameter is included on the associated
CONNECTOR DAMAGE INITIATION option,
only the specified component will undergo damage.
If both this parameter and the COMPONENT parameter on the associated
CONNECTOR DAMAGE INITIATION option are
omitted, only the components of relative motion involved in the associated
CONNECTOR POTENTIAL definition will undergo damage.
- DEGRADATION
Set DEGRADATION=MAXIMUM (default) to indicate that the damage value associated with
this option will be first compared to damage values from other damage
mechanisms (if defined) and that only the maximum value will be considered for
the overall damage.
Set DEGRADATION=MULTIPLICATIVE to indicate that the damage value associated with this option
will contribute multiplicatively to the overall damage.
- DEPENDENCIES
Set this parameter equal to the number of field variable dependencies
included in the definition of the connector damage evolution, in addition to
temperature. If this parameter is omitted, it is assumed that the connector
damage evolution is independent of field variables.
See Material data definition for more information.
- EXTRAPOLATION
Set EXTRAPOLATION=CONSTANT (default unless
CONNECTOR BEHAVIOR, EXTRAPOLATION=LINEAR is used) to use constant extrapolation of the dependent
variables outside the specified range of the independent variables.
Set EXTRAPOLATION=LINEAR to use linear extrapolation of the dependent variables outside
the specified range of the independent variables.
- REGULARIZE
This parameter applies only to
Abaqus/Explicit
analyses.
Set REGULARIZE=ON (default unless
CONNECTOR BEHAVIOR, REGULARIZE=OFF is used) to regularize the user-defined tabular connector
damage data.
Set REGULARIZE=OFF to use the user-defined tabular connector damage data directly
without regularization.
- RTOL
This parameter applies only to
Abaqus/Explicit
analyses.
Set this parameter equal to the tolerance to be used to regularize the
connector damage data.
If this parameter is omitted, the default is RTOL=0.03 unless the tolerance is
specified on the
CONNECTOR BEHAVIOR option.
- SOFTENING
This parameter can be used only in conjunction with TYPE=MOTION.
Set SOFTENING=LINEAR (default) to specify a linear damage evolution law.
Set SOFTENING=EXPONENTIAL to specify an exponential damage evolution law.
Set SOFTENING=TABULAR to specify a damage evolution law in tabular form.
Data lines to define the damage evolution for TYPE=MOTION, SOFTENING=LINEAR
- First line
(needed only if the AFFECTED COMPONENTS parameter is included)
First component of relative motion number that will be damaged.
Second component of relative motion number that will be damaged.
Etc., up to six entries.
- Second line if the AFFECTED COMPONENTS parameter is included; otherwise, first line
Post-initiation equivalent relative plastic motion at ultimate failure if CRITERION=PLASTIC MOTION is specified on the associated
CONNECTOR DAMAGE INITIATION option.
Otherwise, post-initiation constitutive relative motion (displacement/rotation)
at ultimate failure. See
Connector behavior
for a description of the connector relative motions.
Mode-mix ratio if CRITERION=PLASTIC MOTION and the COMPONENT parameter is omitted from the associated
CONNECTOR DAMAGE INITIATION option.
Leave blank otherwise.
Temperature.

components. Repeat the subsequent set of data lines as often as necessary to
define connector damage evolution by specifying the connector relative plastic
or constitutive motion at ultimate failure as a function of mode-mix ratio,
temperature, and other predefined field
variables.
