摘要
Abstract
On basis of the mechanics of interface, singular stress field of interface comer created by reinforcement and elastomer of flexible joint was established. According to interface continuous condition and free boundary condition,the linear equation group of characteristic value A which is related to the singular stress field was obtained. Then, singular stress field and displacement field which include stress intensity coefficient in interface corner of flexible joint were found through solving equation group and deducing formula. At the same time,based on the range of A value,the selection of reinforcement and elastomer as well as geometrical angle with the stress singularity disappearing were presented. The results of singular stress field gained from calculation and finite element method verify the correctness of the analytical solution in this report.关键词
