摘要
用高精度三角形板单元有限元程序研究多种正交各向异性材料开圆孔或开方扎夹支方板的自由振动．分析材料性质、弹性主方向、孔的形状和大小与固有频率、振型的关系，并与各向同性开孔板比较，揭示正交各向异性材料开孔板的动力特性．
The free vibration of orthotropic clamped square plates with a circular or square hole is studied with the help of the program using the high-precision triangular plate bending element. The effect of the material property, the pricipal elasticity direction, the shape and size of the hole on the natural frequencies and modes are discussed, and a comparison with isotropic plates is made, so that dynamic characteristics of orthotropic plates with a hole are obtained.
