Elasto-plastic stress analysis in an adhesively bonded single-lap joint

Abstract

In this study, an analytical elasto-plastic stress analysis was proposed to determine the shear stress in a ductile adhesively bonded single-lap joint. DP460 adhesive was employed in the present study. The von-Mises criterion was used for checking the yield condition of the adhesive material. In the solution, the shear stress was assumed to be constant across the thickness of the adhesive. Bending moment was neglected in the solution. Analytical results were checked by using the finite element analysis. ANSYS 10 was employed in the numerical solution. Analytical and numerical solutions are found to be in a good agreement.
