- If *coupling*=UNCOUPLED, the table data specify the following:
- Stiffness coefficient in the normal direction, Knn.
- Stiffness coefficient in the first shear direction, Kss.
- Stiffness coefficient in the second shear direction, Ktt.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.
- Etc.
- If *coupling*=COUPLED, the table data specify the following:
- Stiffness coefficient in the normal direction, Knn.
- Stiffness coefficient in the first shear direction, Kss.
- Stiffness coefficient in the second shear direction, Ktt.
- Coupled stiffness coefficient, Kns.
- Coupled stiffness coefficient, Knt.
- Coupled stiffness coefficient, Kst.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.

Parameters
----------
repeatedContacts
A Boolean specifying whether to enforce cohesive behavior for recurrent contacts at
nodes on the secondary surface subsequent to ultimate failure. The default value is OFF.
eligibility
A SymbolicConstant specifying the eligible secondary nodes. Possible values are
ALL_NODES, INITIAL_NODES, and SPECIFIED. The default value is ALL_NODES.
defaultPenalties
A Boolean specifying whether to use the default contact penalties. The default value is
ON.
coupling
A SymbolicConstant specifying whether the traction-separation coefficients are coupled
or uncoupled. This argument is valid only for *defaultPenalties*=OFF. Possible values
are UNCOUPLED and COUPLED. The default value is UNCOUPLED.
temperatureDependency
A Boolean specifying whether the coefficient data depend on temperature. This argument
is valid only for *defaultPenalties*=OFF. The default value is OFF.
dependencies
An Int specifying the number of field variables. This argument is valid only for
*defaultPenalties*=OFF. The default value is 0.
table
A sequence of sequences of Floats specifying the traction-separation coefficients. The
items in the table data are described below. This argument is valid only for
*defaultPenalties*=OFF.
Returns
-------
