Finite Element Analysis of Mono- and Bi-Adhesively Bonded Functionally Graded Adherend

Techical Article---Peer Reviewed

Abstract

The stress concentration at the end of bonded lap joints is a major concern in the design and application of adhesive joints, and, therefore, many research works have been carried out to reduce the stress level in the bond line. Most of the proposed methods focus on changing adhesive geometries or properties to achieve an optimized model. In this paper, the stress and strain distribution for adherend with functionally graded properties was analyzed to investigate the effect of the adherend material properties and the type of joint on the stress distribution within bond line. The effect of ceramic volume fraction of the functionally graded materials (FGMs) on the stress concentration has been studied. Also, bi-adhesive joint is used as an alternative stress reduction technique for the joint. Results show that using bi-adhesively joint technique together with high-ceramic volume fraction FGMs can significantly reduce the shear and peel stress in the lap joint.
