功能梯度材料具有复杂的细部结构，其内部构造远比匀质材料复杂.因此，以目前的实验条件，逐点测量功能梯度材料参数的宏观分布曲线是十分困难的.在利用有限体积法求解一维瞬态波传播理论的基础上，结合D．S．C 算法构建了反演数学模型.并通过算例分析在已知接收波的情况下，对功能梯度材料参数3种常用的宏观分布函数进行反演分析，并取得满意结果.显然，这可大大减少功能梯度材料的基本力学性能测试工作.
There are complex microstructures of functionally graded materials,and its internal structure was more complex than the homogeneous material’s.It was difficult to point by point test the parameters distribu-tion of functionally graded materials according to the experimental conditions.In this paper,based on the finite volume method for solving one-dimensional transient wave propagation theory,combined with the DSC algo-rithm to construct inversion mathematical model.In the case of the received wave was known,the inversion a-nalysis for three commonly used macro-distribution function of functionally graded material parameters were completed by the examples,and achieved satisfactory results.Clearly,this method can greatly induce the test work of the basic mechanical performance of functionally graded materials.
