先定义各个失效模式下的刚度矩阵，如基体拉伸失效就定义dagmatrix（nblock），按照你的退化方式用if语句判断，符合条件就把相应刚度赋予折减后的值(Define the stiffness matrix of each failure mode first, if the matrix tensile failure defines the dagmatrix (nblock), according to your degradation mode judged by if statement, accord with the conditions of the corresponding stiffness given reduced value)

Laurent程序,用于CPM信号的调制,接收和分解,译码,以及判断(Laurent procedures for CPM modulation of the signal, and decomposition receiving, decoding, and to determine)

给定模型的层数以及每层的控制点，就可以得到所需模型。(Given the number of layers of the model and the control points of each layer, the desired model can be obtained.)
