Abstract
<p>The interface stress distributions in band scarf adhesive joints with similar and dissimilar adherends under static bending moments are analyzed using three-dimensional finite element calculations. It is found that the maximum principal stress decreases as Young's modulus ratio E1/E2 between the dissimilar adherends decreases, as the adhesive Young's modulus increases, as the adhesive thickness increases, and as the number of bonded interface parts decreases. The number N is optimal as N=2. It is observed that the maximum principal stress is minimal when the scarf angle θis around 60˚, therefore the joint strength of band scarf adhesive is assumed to be maximal for scarf angle of 60˚. The maximum principal stress in the joint with two interface bonded parts subjected to linear stress distributed to partial region is smaller than that distributed to the whole region. The strength of the band scarf adhesive joint with the 30% reduced interface bonded area is approximately the same asthat with the completely bonded area at the interfaces. The strains in the adherends and the joint strengths were measured in the experiments. The measured strains and joint strengths are in fairly good agreement with those obtained from 3-D FEM calculations.</p>
