摘要
本文利用弹性纵波理论,讨论应力波在裂纹处的反射和透射规律,从而根据应力波反射时间和强度确定出裂纹的位置和大小.计算和实验结果表明该理论模型和方法在测试中是有效的.
In this paper, with the aid of the thorey of elastic longtiudinal waves.we discuss laws of wavereflection and transmission on the crack. Acording to the time and intensity of the wave reflection, theposition and size of the crack can be determined. Results of the conputations and the experiments showthat the theory and method are efficacious in tests.
