A Boolean specifying whether the data depend on temperature. The default value is false.
An Int specifying the number of field variables for the data. The default value is 0.
An odb_String specifying the exponential decay definition for the data. Possible values are "COEFFICIENTS" and "TEST_DATA". The default value is "COEFFICIENTS".
The string "NONE" or a Double specifying no upper limit or the friction coefficient shear stress limit. The default value is "NONE".
An odb_String specifying the method for modifying the allowable elastic slip. Possible values are "FRACTION" and "ABSOLUTE_DISTANCE". The default value is "FRACTION".
This argument applies only to Abaqus/Standard analyses.
A Double specifying the ratio of the allowable maximum elastic slip to a characteristic model dimension. The default value is 10–4.
This argument applies only to Abaqus/Standard analyses.
The string "NONE" or a Double specifying the absolute magnitude of the allowable elastic slip. The default value is "NONE".
This argument applies only to Abaqus/Standard analyses.
An odb_SequenceSequenceDouble specifying the tangential properties. Items in the table data are described below. The default value is an empty sequence.
Table data
If formulation=PENALTY, the table data specify the following:
Friction coefficient in the slip direction, 
.
Slip rate, if the data depend on slip rate.
Contact pressure, if the data depend on contact pressure.
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 formulation=EXPONENTIAL_DECAY and exponentialDecayDefinition=COEFFICIENTS, the table data specify the following:
Static friction coefficient, 
.
Kinetic friction coefficient, 
.
Decay coefficient, 
.
If formulation=EXPONENTIAL_DECAY and exponentialDecayDefinition=TEST_DATA, the table data specify the following:
Static coefficient of friction.
Dynamic friction coefficient measured at the reference slip rate, 
.
Reference slip rate, , used to measure the dynamic friction coefficient.
Kinetic friction coefficient, 
. This value corresponds to the asymptotic value of the friction coefficient at infinite slip rate, 
.
