紧固件孔周应力的一种有限元分析方法

Analysis method of fastener hole hole circle stress in FEM

对紧固件孔周应力分析，用有限元法先进行总体计算，再进行孔周详细应力分析．在总体计算时采用二维紧固件元来模拟受剪紧固件．

This paper analyses the stress of fastener hloe circle in the finite element method that first calculates the whole,then analyses stress of hole circle in detail. When calculating the whole,sheared fastener are simulated by two--dimension fastener element.
