含孔复合材料层合板的轴压稳定性

Stability Aualsis of Holed Composite Lamination Plates under Axial Compression

本文对含孔纤维增强复合材料对称角铺设层合板的轴压稳定性进行了分析计算和实验研究,证实含孔复合材料层合板在轴压载荷作用下,其失效模式主要是圆孔附近的局部屈曲,并得到了临界载荷值与铺层角和孔径板宽比之间的关系。

This paper studies the axial compression stability of holed composite lamination plates which were symmetric angle laid. The analytical and experimental results show that the failure mode of holed composite lamination plates under axial compression were mainly local buckling, and the critical loads for holed composite lamination plates is related to the ratio of hole diameter to plate width and laid angle.
