Effect of fillet on bi-adhesive bonded aluminum lap joints

The effect of fillet formed from structural adhesive differing in elastic modulus on the stress distribution along the length of bi-adhesive bonded single lap aluminum joints was studied under the condition of one adhesive or bi-adhesive arranged along the bondline by an elastic finite element model. The results obtained from the numerical simulation show that the fillet can reduce the peak value of stress obviously. It is not recommended to...
