| 摘 要： | 本文从弹性波理论出发。导出了微正交各向异性材料平面应力问题的应力—声关系。借助于一个新引进的参数S,给出了一个独立的新方程,使这类问题的解决大为简化。在实验技术方面,研制了垂直入射平面偏振横波的可旋转换能器,建立了平面声弹性实验系统,改进了耦合和测速技术。

| Abstract: | In this paper, the stress-acoustic relations of slightly orthotropic materials have been derived according to elastic waves theory. By introducing a new parameter S and another independent equation, this kind of problems would be simplified. On the experimental techniques: a plane-polarized ultrasonic shear wave rotatable transducer (RPT) has been designed; an experimental system has been set up; and the coupling as well as velocity measuring techniques were improved. |
