摘要

研究了平面声波脉冲在弹性圆柱薄壳上沿无限长裂纹的二维散射问题。壳里面是空的，外面被水包围。用Kirchhoff - Love理论描述弹性壳的动力平衡。研究了壳体缺陷对回波信号结构的影响。

Acoustic echo-signal from a thin cylindrical shell with a slit

The two-dimensional problem of plane sound wave impulse scattering on the thin elastic circular cylindrical shell cracked along its infinite length. The shell is empty inside and surrounded by water from outside. The Kirchhoff - Love theory for description of elastic shell dynamic equilibrium is used. The shell defect influence on the echo-signal structure is investidated.
