Numerical Analysis of Bi-Adhesive Boded Single Lap Composite Joint with Mechanics Analysis

Article Preview

Abstract:

The effect of dual adhesives with different length ratio on the stress distributed in adhesively bonded single lap steel joint was investigated using elasto-plastic finite element method (FEM). The results from the numerical simulation showed that the peak stress along the bondline moves from the ends of the overlap to the middle part of lap zone. Compared with the results from the mono-adhesive system, appropriate bond-length ratios is beneficial to optimize the stress distribution and it is 0.4 for bi-adhesive bonded single lap composite joint.
