Abstract
In this study, we have newly proposed some joint configurations to improvement of tensile shear strength of the adhesively single-lap joint, and we named that "Five holes crosswise arranged joint". Mechanical property in the presented joint subjected to static tensile load was analyzed, using Finite Element Method. FEM analyses were carried out to clarify the stress distribution at the bonded part. To evaluation the tensile shear strengths of various joints, tensile experiments were performed by universal test machine. As a numerical result, it was found that stress concentrations occur at near the adherend holed parts in adhesive layer. From the tensile experiments, it was also proved that the fracture load of five holes crosswise arranged joint becomes increase than conventional joint.
