        Parameters
        ----------
        initTable
            A sequence of sequences of Floats specifying the value defining the fracture criterion. 
            The items in the table data are described below. 
        type
            A SymbolicConstant specifying the type of data used to define the fracture criterion. 
            Possible values are VCCT and ENHANCED VCCT. The default value is VCCT. 
        mixedModeBehavior
            A SymbolicConstant specifying the mixed mode behavior type used to define fracture 
            criterion. Possible values are BK, POWER, and REEDER. The default value is BK. 
        temperatureDependency
            A Boolean specifying whether the fracture criterion data depend on temperature. The 
            default value is OFF. 
        dependencies
            An Int specifying the number of fracture criterion data field variables. The default 
            value is 0. 
        tolerance
            A Float specifying the tolerance for VCCT\Enhanced VCCT type. The default value is 0.2. 
        specifyUnstableCrackProp
            A SymbolicConstant specifying whether to include unstable crack growth tolerance in 
            fracture criterion. Possible values are ON and OFF. The default value is OFF. 
        unstableTolerance
            The SymbolicConstant DEFAULT or a Float specifying the tolerance for unstable crack 
            propagation. This parameter specified only if *specifyUnstableCrackProp*=ON. The default 
            value is DEFAULT.
