弱各向异性介质弹性波的准各向同性近似正演模拟
For an anisotropic or isotropic plate containing an elliptical hole, the hoop stress around the hole subject to arbitrarily concentrated forces or distributed forces on its surface is derived with a complex variable function method.
应用复变函数的方法，对于含有椭圆孔的各向异性板或各向同性板，导出了当椭圆孔周作用任意集中力或分布力时孔周周向应力的解析表达式；其特例与前人结果一致。
Based on the differential equation of the deformed surface of the orthotropic plate,one principal direction size is kept invariably,then another principal direction size is transformed linearly,maintains elasticity coefficient is kept the same as that of the first principal direction E=E_1,Poisson ratio μ=μ_1μ_2~(1/2),thus the original orthogonal plate can be equivalent to an isotropic plate.
通过分析得到了现浇混凝土空心板正交各向异性主刚度存在着D3=D1D2~(1/2)的关系;从正交各向异性板挠曲面的偏微分方程出发,保持一个主方向尺寸不变x1=x,将另一主方向的尺寸做线性缩放y1=k-14y,并保持弹性模量与第一主方向相同E=E1,泊松比μ=μ1μ2~(1/2),将原来的正交各向异性板等效为一块各向同性板,通过分析得到:各向同性板任意点的挠度就是原正交各向异性板对应点的挠度,各对应点内力存在简单的对应关系:Mx=Mx1、My=k1/2My1、Mxy=k1/4Mx1y1。

Since the isotropy of such laminates holds only for the elastic properties, but not for the strength behavior, their strength largely depends on the stacking structure.
