| 摘 要： | 用里兹法确定在单轴载荷条件下具有单一脱层的对称正交铺设层合板脱层屈曲的临界屈曲载荷。脱层区域假定为椭圆形状,同时研究脱层部分的厚度、半轴比和子层角对于临界屈曲载荷的影响,分析预见的临界载荷与已有结果基本吻合。

| Abstract: | The Rayleigh-Ritz method is used to calculate the critical load at which delamination buckling will occur for a symmetric cross-ply composite laminate containing a single delamination.The delamination is assumed to be elliptical in shape.In this paper the critical load of delamination buckling for a symmetric cross-ply laminate acted on by uniaxial load is investigated. The effects of the thickness and the ratio of semiaxes of delamination region,and sublaminate angle,and ratio of loads on the critical load are considered.The analytical predictions for delamination buckling load are more consistent with results existing in literatures. |
