The CohesiveBehavior object specifies cohesive behavior for a contact interaction property.
import interaction mdb.models[name].interactionProperties[name].cohesiveBehavior
This method creates a CohesiveBehavior object.
mdb.models[name].interactionProperties[name].CohesiveBehavior
Required arguments
Optional arguments
A Boolean specifying whether to enforce cohesive behavior for recurrent contacts at nodes on the slave surface subsequent to ultimate failure. The default value is OFF.
A SymbolicConstant specifying the eligible slave nodes. Possible values are ALL_NODES, INITIAL_NODES, and SPECIFIED. The default value is ALL_NODES.
A Boolean specifying whether to use the default contact penalties. The default value is ON.
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.
A Boolean specifying whether the coefficient data depend on temperature. This argument is valid only for defaultPenalties=OFF. The default value is OFF.
An Int specifying the number of field variables. This argument is valid only for defaultPenalties=OFF. The default value is 0.
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.
Table data
If coupling=UNCOUPLED, the table data specify the following:
Stiffness coefficient in the normal direction, 
.
Stiffness coefficient in the first shear direction, 
.
Stiffness coefficient in the second shear direction, 
.
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.
