ConnectorPotential#

class ConnectorPotential(componentStyle: SymbolicConstantType = 'COMPONENT_NUMBER', componentNumber: int = 0, sign: SymbolicConstantType = 'POSITIVE', scaleFactor: float = 1, positiveExponent: float = 2, shiftFactor: float = 0, hFunction: SymbolicConstantType = 'ABS')[source]#

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.
