        ----------
        table
            A sequence of sequences of Floats specifying the items described below. 
        rate
            A Boolean specifying whether the data depend on rate. The default value is OFF. 
        type
            A SymbolicConstant specifying the type of postcracking behavior data. Possible values 
            are: 
            - STRAIN, specifying postfailure stress as a function of cracking strain. 
            - DISPLACEMENT, specifying postfailure stress as a function of cracking displacement. 
            - GFI, specifying failure stress as a function of the fracture energy. 
            The default value is STRAIN. 
        temperatureDependency
            A Boolean specifying whether the data depend on temperature. The default value is OFF. 
        dependencies
            An Int specifying the number of field variable dependencies. The default value is 0.
