摘要: 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 S4 S4 and S4 S2 boundary conditions. The results show that the effects of absolute value and the sign of the coupling coefficient on the stability behavior of the paules are significant.
