Three-Dimensional Non-Linear FE Analysis of Shear Stress Distributions in Adhesively Bonded Joint

The aim of this work is to investigate the shear stress distributions across the adhesive layer thickness in single-lap adhesively bonded joint. The shear stress distributions of a single-lap adhesively bonded joint have been investigated using the three-dimensional linear static and non-linear quasi-static finite element method. The analysis results indicate that there are significant differences between the linear static and non-linear quasi-static analyses. The results also show that the maximum value of the shear stress component S13 occurs at the centre line while the maximum of the shear stress components S12 and S23 occur near or at the left-rear corner of the adhesive layer.
