| 摘 要： | 采用考虑横向剪切变形的三角形拟协调罚函数单元，研究了复合材料层合板在压 剪载荷作用下的初始屈曲及其后屈曲特性。数值计算表明：该单元具有良好的收敛性 和较高的精度；横向剪切对层合板后屈曲路径的影响是不可忽视的。同时，还讨论了 边界等件、加载方式、剪切力的方向及初始缺陷的影响。

| Abstract: | A fifteen-variables quasi-conforming triangle element technique including transverse shear effect for penalty-finite clement method is used to study the compressive-shear stability and postbuckling behavior of composite laminated panels with arbitrary shapes and ply confiqurations. The calculation results show that this element has a good convergence and precision, and the ignorance of transverse shear effect is not allowed. The effects of boundary conditions, loading forms, shear directions and initial imperfaction are also discussed. |
