摘要
根据相关文献,将拟Shannon小波配置法应用到环扇形板的混合状态方程中,构造出了环扇形板平面方向离散,而厚度方向是解析的混合状态方程。因为用拟Shannon小波张量积表示的近似解是离散形式的,所以固支边界的未知应力可以近似地用内点的应力和位移来表示。数值实例验证了本文方法的正确性。
Based upon the relative references, the mixed state equation of elastic annular sector plate, which was discreted in plane and hold the continuity along the thickness, was established by employing the quasi- shannon wavelet collocation method. Because of the discrete form of the approximate solution which is expressed by the tensor of the Quasi-shannon wavelet, the unknown stress of the clamped boundary can be expressed by the stress and displacement of inner nodes. Numerical results confirmed that the approach in this paper is correct.
