ConnectorPotential#

class ConnectorPotential(componentStyle=abaqusConstants.COMPONENT_NUMBER, componentNumber=0, sign=abaqusConstants.POSITIVE, scaleFactor=1, positiveExponent=2, shiftFactor=0, hFunction=abaqusConstants.ABS)[source]

It can be used only in conjunction with ConnectorDamage, ConnectorFriction, and ConnectorPlasticity objects.

class ConnectorOptions(useBehRegSettings=ON, regularize=ON, defaultTolerance=ON, regularization=0, defaultRateFactor=ON, rateFactor=0, interpolation=abaqusConstants.LINEAR, useBehExtSettings=ON, extrapolation=abaqusConstants.CONSTANT)[source]

The ConnectorOptions object is used to define various options for connector behaviors. It can be used only in conjunction with CDCTerm, ConnectorDamage, ConnectorDamping, ConnectorElasticity, ConnectorFriction, and ConnectorPlasticity objects. Because the ConnectorDamage object contains two separate ConnectorOptions repositories (one for damage initiation and one for damage evolution), there are two ConnectorOptions constructors associated with that behavior—initiationOptions and evolutionOptions. The ConnectorPlasticity object also contains two separate ConnectorOptions repositories (one for isotropic hardening and one for kinematic hardening), so there are two ConnectorOptions constructors associated with that behavior—isotropicOptions and kinematicOptions.

class TangentialBehavior(formulation=abaqusConstants.PENALTY, slipRateDependency=OFF, pressureDependency=OFF, temperatureDependency=OFF, dependencies=0, exponentialDecayDefinition=abaqusConstants.COEFFICIENTS, shearStressLimit=None, maximumElasticSlip=abaqusConstants.FRACTION, fraction=None, absoluteDistance=None, table=())[source]

The TangentialBehavior object specifies tangential behavior for a connector friction behavior option.

Note

This object can be accessed by:

import section
mdb.models[name].sections[name].behaviorOptions[i].tangentialBehavior
import odbSection

The table data for this object are:

If formulation = PENALTY, the table data specify the following:
- Friction coefficient in the slip direction, μμ.
- 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, μsμs.
- Kinetic friction coefficient, μkμk.
- Decay coefficient, dcdc.
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, ˙γ2γ˙2.
- Reference slip rate, ˙γ2γ˙2, used to measure the dynamic friction coefficient.
- Kinetic friction coefficient, μ∞μ∞. This value corresponds to the asymptotic value of the friction coefficient at infinite slip rate, ˙γ∞γ˙∞.
