应用广义虚载荷法求解反对称角铺设层合板的弯曲

THE GENERALIZED VIRTUAL LOAD METHOD FOR BENDING PROBLEMS OF UNSYMMETRIC ANGLE-PLY PLATES

本文应用广义虚载荷法结合富里叶级数，得到了各种边界条件下反对称角铺设层合板弯曲问题的富里叶级数解。同时给出了加快级数收敛的公式以及逐项微分富里叶级数任意次的方法。

This paper presents a Fourier series solution for bending problems of unsymmetricangle-ply plates with various boundary conditions,using the generalized virtual loadmethod. Moreover,the formulation for accelerating convergence of Fourier series and themethod for differentiating the series,item by item and arbitrary times, are given.
