【摘要】 本文根据Reddy的三阶剪切变形理论,导出了该理论下对称角铺设层合板非线性弯曲问题的控制微分方程组,并在四边固支边界条件下,用摄动法对上述微分方程组进行了求解。针对不同的层合板参数进行了大量的数值计算,并与经典弯曲理论下的结果进行了比较,得到一些有意义的结果。更多还原

【Abstract】 A higher-order shear deformation theory is used to analyse nonlinear bending of symmetrically laminated angle-ply rectangular plates. The nonlinear governing differential equations are solved here by using perturbation method. Numerical rerults are presented graphically for vairous parameters of laminated plate. The present solutions are compared with those obtained using the classical plate theory. A lot of significient conclusions are obtained.更多还原
