摘要
本文用动态松弛法（ＤＲＭ）研究了压弯耦合对承受均匀单轴压力作用的非对称叠层复合材料圆柱微曲板在加载和卸载过程中的非线性稳定特性的影响·给出了Ｓ４Ｓ４和Ｓ４Ｓ２边界条件下十字叠层平板和曲板的数值计算结果·计算结果表明。
Dynamic_Relaxation Method(DRM) is applied to studying the influence of compression_bending coupling on nonlinear behavior of cylindrically slightly curved panels of unsymmetric laminated composite materials subjected to uniform uniaxial compression during loading and unloading. Numerical results are given for cross_ply plates and panels under S4S4 and S4S2 boundary conditions. The results show that the effects of absolute value and the sign of the coupling coefficient on the stability behavior of the panels are significant.
