Stress analysis of adhesive bonded tee joints W. Li, L. Blunt, KJ. Stout University ofBirmingham, Birmingham B15 2TT, UK Abstract The stresses in adhesive bonded Tee joints, subjected totwo linear and one bending moment loads, have been analysed using finite element method. It was assumed that the adhesive and adherends had linear elastic properties. The influences on the stress distributions of the overlap length, adhesive thickness and the fillet of the angle plate are investigated. It was found that experimental results were in good agreement with those of the FE analysis. Introduction The technology of adhesive bonded joints is currently employed in many structural components and machine elements toimprove the joint performance. The possible use of adhesive bonded joints in a new engineering design should always be considered, due to light weight, stiff structure and possible economic benefits. Adhesive bonding skills are still not widely applied in practice, this limitation is due to the difficulty in predicting the performance of bonding joints. Since the first classical mechanics analysis of the single-lap joints was carried out by Volkersen in 1938, studies on different types of adhesive bonded joints, such as butt joint, tubular joints, corner joints and so on, have been carried out. There has however been no studies carried out on adhesive bonded Tee joints until now. Based on the fact that failure of joints initiates where high stresses (particularly peel stresses) occur, a stress analysis of adhesive bonded Tee joints has been carried out to determine the optimum dimensions of the joints. This paper presents a theoretical analysis of adhesive bonded Tee joints by the finite element method.The effect of adhesive thickness, overlap length and form of angle plate bend also had been investigated. The results have then been compared to experimental results. Joints configuration and theoretical analysis The adhesive bonded joint used inthe study was Tee joint.
