Required parameters
- NAME
-
Set this parameter equal to a label that will be used to refer to the derived component.
Optional parameters
- DEPENDENCIES
-
Set this parameter equal to the number of field variable dependencies included in the definition of the connector derived component, in addition to temperature. If this parameter is omitted, it is assumed that the connector derived components are 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.
- INDEPENDENT COMPONENTS
-
Set INDEPENDENT COMPONENTS=POSITION (default) to specify dependencies on components of relative position included in the derived component definition.
Set INDEPENDENT COMPONENTS=CONSTITUTIVE MOTION to specify dependencies on components of constitutive relative motion included in the derived component definition.
- OPERATOR
-
Set OPERATOR=NORM (default) to use a square root of a sum of the squares function of the contributing components.
Set OPERATOR=MACAULEY SUM to sum the contributing components with a Macauley bracket function applied to each contribution.
Set OPERATOR=SUM to sum the contributing components directly.
- 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 derived component data.
Set REGULARIZE=OFF to use the user-defined tabular connector derived component 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 derived component data.
If this parameter is omitted, the default is RTOL=0.03 unless the tolerance is specified on the CONNECTOR BEHAVIOR option.
- SIGN
-
Set SIGN=POSITIVE (default) to provide an overall positive sign to the derived component definition.
Set SIGN=NEGATIVE to provide an overall negative sign to the derived component definition.
Data lines to define the derived component if the INDEPENDENT COMPONENTS parameter is omitted
- First line
First component number (1–6) to be used in the definition of the derived component.
Second component number (1–6) to be used in the definition of the derived component.
Etc., up to entries (maximum six).
- Subsequent lines
Scaling constant () that multiplies the first component identified on the first data line.
Scaling constant () that multiplies the second component identified on the first data line.
Etc., up to entries as identified on the first data line.
Temperature.
First field variable.
Second field variable.
Etc., up to eight entries per line.
- If the number of data entries exceeds the limit of eight entries per line, continue the input on the next data line.
Do not repeat the first data line. Repeat the subsequent data lines as often as necessary to define the contributions to the derived component as a function of temperature and field variables.
Data lines to define the derived component if the INDEPENDENT COMPONENTS parameter is included
- First line
First independent component number (1–6).
Second independent component number (1–6).
Etc., up to entries (maximum six).
- Second line
First component number (1–6) to be used in the definition of the derived component.
Second component number (1–6) to be used in the definition of the derived component.
Etc., up to entries (maximum six).
- Third line
Scaling constant () that multiplies the first component identified on the second data line.
Scaling constant () that multiplies the second component identified on the second data line.
Etc., up to entries as identified on the second data line.
Connector relative position or constitutive relative motion in the first independent component identified on the first data line.
Connector relative position or constitutive relative motion in the second independent component identified on the first data line.
Etc., up to entries as identified on the first data line.
Temperature.
First field variable.
- If the number of data entries exceeds the limit of eight entries per line, continue the input on the next data line.
- Continuation line (if needed)
Second field variable.
Etc., up to eight entries per line.
Do not repeat the first two data lines. Repeat the subsequent data lines as often as necessary to define the contributions to the derived component as a function of connector relative position or constitutive relative motion, temperature, and field variables.
