| 摘 要： | 本文在分层屈曲的位移表达式中,考虑了反映拉剪耦合与弯扭耦合效应的高阶项.文中还讨论了层板两端在均匀位移拉伸作用下发生分层屈曲的机理,并分析了分层屈曲应变与母层板和子层板的参数之间的关系.

| Abstract: | In this paper the buckling charactristics of near-surface 2-Ddelamination in a symmetrical laminate is investigated.In the displacementfunctions of the delamination buckling,it is assumed that the effects of stre-tching-shearing coupling and bending-twisting coupling are characterizedby the nonsymmetrical high-order terms.The mechanism of delaminationbuckling under the uniform displacement stretching at the two ends of lami-nate is discussed.Also the relation between the strain of delamination bucklingand the parameters of the parent laminate and the sublaminate is analyzed. |
