摘要
用动态松弛法研究了剪弯耦合对四边承受均匀剪力的复合材料非对称角铺设叠层圆柱微曲板稳定性的影响,讨论了铺层顺序、曲率、边界条件及剪力方向所引起的效应。结果表明,耦合系数B16、B26的正负符号与绝对值对板的稳定性的影响是十分显著的。
Dynamic Relaxation Method (DRM) is applied to study the influence of shear_bending coupling on the nonlinear stability of cylindrically slightly curved panels of unsymmetric angle_ply laminated composite materials subjected to uniform shear forces on its four sides.The effects of ply stacking sequence,curvature,boundary condition and direction of the shear force are discussed.The results show that the stability of the panels is greatly influenced not only by the absolute value but also by the positive and n...
