The StdContactControl object is used in Abaqus/Standard analyses to specify optional solution controls for problems involving contact between bodies.
The StdContactControl object is derived from the ContactControl object.
import interaction mdb.models[name].contactControls[name]
This method creates an StdContactControl object.
mdb.models[name].StdContactControl
Required argument
A String specifying the contact controls repository key.
Optional arguments
A Float specifying the factor by which Abaqus/Standard will scale the default penalty stiffness to obtain the stiffnesses used for the contact pairs. Only contact interactions defined with augmented Lagrangian surface behavior will be affected by this argument. The default value is 1.0.
A SymbolicConstant specifying whether the allowable penetration is an absolute value or a value relative to the characteristic contact surface face dimension. Only contact interactions defined with augmented Lagrangian surface behavior will be affected by this argument. Possible values are RELATIVE and ABSOLUTE. The default value is RELATIVE.
A Float specifying the ratio of the allowable penetration to the characteristic contact surface face dimension. The float values represent percentages (e.g.: 0.001=0.1%). Only contact interactions defined with augmented Lagrangian surface behavior will be affected by this argument. The default value is 10–3.
The relativePenetrationTolerance argument applies only when penetrationTolChoice=RELATIVE. The relativePenetrationTolerance and absolutePenetrationTolerance arguments are mutually exclusive.
None or a Float specifying the allowable penetration. Only contact interactions defined with augmented Lagrangian surface behavior will be affected by this argument. The absolutePenetrationTolerance argument applies only when penetrationTolChoice=ABSOLUTE. The relativePenetrationTolerance and absolutePenetrationTolerance arguments are mutually exclusive. The default value is None.
A SymbolicConstant specifying when the application of friction occurs. Possible values are:
The default value is IMMEDIATE.
IMMEDIATE, specifying the friction is included in the increment when contact occurs.
DELAYED, specifying the application of friction is delayed until the increment after contact occurs.
A Boolean specifying whether Abaqus/Standard should automatically compute an overclosure tolerance and a separation tolerance to prevent chattering in contact. The default value is OFF.
The automaticTolerances argument cannot be used with the maxchp, perrmx, and uerrmx arguments.
An Int specifying the maximum number of points that are permitted to violate contact conditions in any increment. The default value is 0.
Either the perrmx or the uerrmx argument must be specified in conjunction with the maxchp argument.
A Float specifying the maximum value of tensile stress (tensile force in GAP- or ITT-type contact elements) allowed to be transmitted at a contact point. The default value is 0.0.
The perrmx argument must be specified in conjunction with the maxchp argument.
A Float specifying the maximum overclosure distance allowed at a slave node that is considered to be open. The default value is 0.0.
The uerrmx argument must be specified in conjunction with the maxchp argument.
A SymbolicConstant specifying whether or not viscous damping will be specified, and if so, how it will be specified. Possible values are NONE, AUTOMATIC, and COEFFICIENT. The default value is NONE.
A Float specifying the value of the damping factor. This value is multiplied by the calculated damping coefficient. The default value is 1.0.
This argument is only valid when stabilizeChoice=AUTOMATIC.
A Float specifying the damping coefficient. The default value is 0.0.
This argument is only valid when stabilizeChoice=COEFFICIENT.
A Float specifying the tangential stabilization as a fraction of the normal stabilization (damping). The default value is 1.0.
This argument is valid only if stabilizeChoice = AUTOMATIC or COEFFICIENT.
A Float specifying the fraction of the damping that remains at the end of the step. The default value is 0.0.
This argument is valid only if stabilizeChoice = AUTOMATIC or COEFFICIENT.
A SymbolicConstant specifying how the zero-damping clearance will be specified. Possible values are COMPUTE and SPECIFY. The default value is COMPUTE.
This argument is valid only if stabilizeChoice = AUTOMATIC or COEFFICIENT.
None or a Float specifying the clearance at which damping becomes zero. This argument is valid only when zeroDampingChoice=SPECIFY. This argument is valid only if stabilizeChoice = AUTOMATIC or COEFFICIENT. The default value is None.
A SymbolicConstant specifying whether to enforce the contact constraints with Lagrange multipliers. Possible values are DEFAULT, ENFORCEMENT_OFF, and ENFORCEMENT_ON. The default value is DEFAULT.
