摘要
本文采用正交各向异性厚板静力问题的基本解作为边界积分方程的核函数,利用加权残数法建立了正交各向异性厚板振动分析的边界积分方程。文中详细地讨论了边界积分方程的数值处理过程并给出了若干数值算例以论证本文方法的正确性。
In this paper the static fundamental solutions of orthotropic thick plates are taken as the kernel function of boundary integral equation. The boundary integral equations for vibration analysis of orthotropic thick plate; are formulated by the method of weighted residuals. The numerical implemen-tation of boundary integral equations is discussed in detail and serval exam-ples of different boundary conditions are given to demonstrate the correctness of the present method.
