This research develops methods for the nondestructive characterization of mechanical properties of metal matrix composites such as aluminum reinforced with silicon-carbide fibers and measures, in a nondestructive manner, the residual stresses which exist in these materials after manufacturing. This measurement will be attempted by using acoustoelastic methods. Based on the results, a theoretical development of the relations between the acoustoelastic constants with the volume fraction of the reinforcement will be made.

本研究发展了无损表征的方法 金属基复合材料，如铝， 用碳化硅纤维增强，并采取措施， 非破坏性的方式，残余应力存在于这些 制造后的材料。 将尝试进行此测量 使用声弹性方法。 根据结果，理论上 声弹性常数与 将得到增强体的体积分数。
