Stress Distribution in Reverse-Bent Bonded Joint

Article Preview

Abstract:

Adhesively bonding technology is used increasingly by the automotive and aerospace industries. The design of reverse-bent joint is effective way for improving the bonded joint performance. The influence of preformed angle on the stress distribution of the adhesive-adherend interface is studied in this paper using finite element analysis (FEA). By comparing the results of the FEA for reverse-bent joints with different preformed angle, it can be seen that the preformed angle not only have significant influence on the stress distribution of overlap section, but also changes stress concentration at the spew fillet of bonded joint. The results also indicate that there is a best value of preformed angle in which the reverse-bent bonded joint has the best performance.
