RETRACTION: Stress distribution in adhesively bonded scarf joint under thermo-mechanical loads
This article aimed to provide a closed-form solution for the stress distribution in adhesively bonded scarf joints under thermo-mechanical loads. Based on the elasticity theory, the present approach can accurately predict thermo-mechanical stress distributions on both adhesives and adherends layers taking into account the influences of the scarf angle and the adhesive thickness. The accuracy of the present method is highlighted through comparison with finite element solutions of stress distribution under separated and simultaneous thermal and mechanical loads for two configurations of scarf joint. Analytical and numerical results of normal and shear stresses show a good agreement for both configurations. A parametric study is also conducted in order to examine the influence of adhesive thickness and scarf angle on stress distributions in the joints and the joint strength. The results should be relevant to the design and application of adhesive scarf joint.
