摘要
利用光弹方法和制造玻璃内部裂缝的技术,观测了在脉冲纵波掠入射情形下带形裂缝的散射声场,并定量地测量了散射头波的强度分布。实验结果与文献[1]所给出的近似解作了比较,两者符合很好。
On using the dynamic photoelas ic method and our technique of fabricating an internal crack in glass, the scattered wave fields of a grazing longitudinal ultrasonic wave pulse by a ribbontype crack are observed. The distribution of the intensity of the head wave is measured quantitatively. The experimental results fairly agree with the theoretical ones given in Reference [1] .
