| 摘 要： | 本文以板的无量纲最大挠度为摄动参数,应用摄动法研究了在几种支承情况下,反对称角铺设层合矩形板的后屈曲问题,并以梁的特征函数所构成的广义付里叶级数作为高阶摄动偏微分方程的近似解,本文方法简捷,计算收敛性好、数据可靠。

| Abstract: | An analysis for th:postbuckling bahavior of antisymmetrically laminated angle-ply rectangular plates with various boundary conditions is presented by making use of the pertuxbation tschniquc.The nondimensional maximum deflection is selected as.the perturbation parameter. A solution of perturbation differential equation of higher-order approximation is assumed in the form of double Fourier serics consisting of the beam function.This method is very efficient and the i.umcrical results show good convergence and reliability of the present solution. |
