摘要
应用ANSYS软件的层合板单元SHELL91,分别对四层复合材料板在不同铺层情况下,用螺钉与其他构件联接时所产生的孔边应力分布进行有限元法计算和分析,最后指出应力分布情况将随着不同铺层结构而发生变化。
For the case of the four-layer plates laminated in several different directions, the analyses of stress distribution around the hole which is used for the screw to join to other parts are calculated by the element, SHELL 91 in ANSYS6.1. Then, features of the stress distribution for the four-layer plate structure are presented.
