Numerical and Analytical Investigations on The Stress Distributions in Single-Lap Joints

The objective of this paper is to compare the shear and peel stress distributions in the single lap joints obtained using analytical model with those obtained using numerical analysis. The Zhao’s closed form solution that includes the bending moment effect was used as an analytical model. In the numerical analysis, two dimensional finite element model with plane strain assumption was used. Analyses were performed for brittle and ductile adhesive types both analytically and numerically. In addition, a comparison of peak shear and peak peel stress values was carried out on the basis of percentage error. The results show that both analytical and numerical analyses were in very close agreement.
