Parameters
----------
intrinsicComponents
A sequence of Ints specifying the components of relative motion for which the
contributing term is defined. Possible values are 1 ≤≤ *intrinsicComponents* ≤≤ 6. Only
available components can be specified if the DerivedComponent object is being referenced
by a Potential object. This is not the case if the DerivedComponent object is referenced
by a ConnectorFriction object directly. The default value is an empty sequence.
table
A sequence of sequences of Floats specifying components numbers and temperature and
field values. Each sequence of the table data specifies:The first intrinsic component
number.If applicable, the second intrinsic component number.Etc.If applicable, the first
independent component number.If applicable, the second independent component
number.Etc.If applicable, the temperature value.If applicable, the value of the first
field variable.If applicable, the value of the second field variable.Etc.The default
value is an empty sequence.
termOperator
A SymbolicConstant specifying the method for combining contributing terms: square root
of a sum of the squares, direct sum, or Macauley sum. Possible values are RSS, SUM, and
MACAULEY. The default value is RSS.
termSign
A SymbolicConstant specifying the overall sign for the contributing term. Possible
values are POSITIVE and NEGATIVE. The default value is POSITIVE.
localDependency
A Boolean specifying whether the table data depend on either components of relative
position or components of constitutive relative motion. The default value is OFF.
indepCompType
A SymbolicConstant specifying whether localDependency refers to components of relative
position or components of constitutive relative motion. Possible values are POSITION and
MOTION. The default value is POSITION.The *indepCompType* argument applies only if
*localDependency*=ON.
indepComponents
A sequence of Ints specifying the independent components included in the derived
component definition. Possible values are 1 ≤≤ *indepComponents* ≤≤ 6. Only available
components can be specified. The *indepComponents* argument applies only if
*localDependency*=ON. The default value is an empty sequence.
tempDependency
A Boolean specifying whether the table data depend on temperature. The default value is
OFF.
fieldDependencies
An Int specifying the number of field variable dependencies. The default value is 0.

Parameters
----------
useBehRegSettings
A Boolean specifying whether or not to use the behavior-level settings for
regularization options. This argument is applicable only for an Abaqus/Explicit
analysis. The default value is ON.
regularize
A Boolean specifying whether or not the tabular data will be regularized. This argument
is applicable only for an Abaqus/Explicit analysis and only if *useBehRegSettings*=OFF.
The default value is ON.
defaultTolerance
A Boolean specifying whether or not the analysis default regularization tolerance will
be used. This argument is applicable only for an Abaqus/Explicit analysis and only if
*useBehRegSettings*=OFF and *regularize*=ON. The default value is ON.
regularization
A Float specifying the regularization increment to be used. This argument is applicable
only for an Abaqus/Explicit analysis and only if *useBehRegSettings*=OFF,
*regularize*=ON, and *defaultTolerance*=OFF. The default value is 0.03.
defaultRateFactor
A Boolean specifying whether or not the analysis default rate filter factor will be
used. This argument is applicable only for an Abaqus/Explicit analysis that includes
isotropic hardening with tabular definition or damage initiation with Plastic motion
criteria. The default value is ON.
rateFactor
A Float specifying the rate filter factor to be used. This argument is applicable only
for an Abaqus/Explicit analysis that includes isotropic hardening with tabular
definition or damage initiation with Plastic motion criteria. This argument is also
applicable only if *defaultRateFactor*=OFF. The default value is 0.9.
interpolation
A SymbolicConstant specifying the type of interpolation increment to be used on
rate-dependent tabular data. This argument is applicable only for an Abaqus/Explicit
analysis that includes isotropic hardening with tabular definition or damage initiation
with Plastic motion criteria. Possible values are LINEAR and LOGARITHMIC. The default
value is LINEAR.
useBehExtSettings
A Boolean specifying whether or not to use the behavior-level settings for extrapolation
options. The default value is ON.
extrapolation
A SymbolicConstant specifying the extrapolation technique to be used. This argument is
applicable only if *useBehExtSettings*=OFF. Possible values are CONSTANT and LINEAR. The
default value is CONSTANT.
