class ConnectorOptions( useBehRegSettings=1, regularize=1, defaultTolerance=1, regularization=0, defaultRateFactor=1, rateFactor=0, interpolation=LINEAR, useBehExtSettings=1, extrapolation=CONSTANT, )[source]¶

Bases: object

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

Bases: object

The ConnectorPotential object is used to define a restricted set of mathematical functions to represent yield or limiting surfaces in the space spanned by connector available components. It can be used only in conjunction with ConnectorDamage, ConnectorFriction, and ConnectorPlasticity objects. Because the ConnectorDamage object contains two separate ConnectorPotential repositories (one for damage initiation and one for damage evolution), there are two ConnectorPotential constructors associated with that behavior—IniPotential and EvoPotential.
