【摘要】 应用能量法研究了对称铺层的闭合圆柱形层合壳体的表层矩形分层屈曲特性,分析了母层壳、子层壳的几何、物理参数同分层屈曲临界应变值之间的关系,探讨了拉伸分层屈曲形成的机制及其层合圆柱壳体中面曲率对分层屈曲的影响.更多还原

【Abstract】 In this paper,the buckling characteristics of near surface rectang-ular delamination in a symmetric close cylindrical laminated shell is investi-gated by using the energy method.The relationships between critical strainvalue and the parameters of geometry and physics are studied.Also,theformation mechanism of tension delamination bucklion buckling and the infl-uence of cylindrical shell curvature for the delamination buckling are appr-oached.更多还原
