A TWO-DIMENSIONAL STRESS ANALYSIS OF A BUTT ADHESIVE JOINT CONTAINING CIRCULAR HOLES AND RIGID FILLERS IN AN ADHESIVE SUBJECTED TO A TENSILE LOAD

摘要

This study deals with a stress analysis of a butt adhesive joint which contains circular holes and rigid fillers in the adhesive and is subjected to a tensile load. In the analysis, the adherends are assumed to be rigid and the adhesive is replaced with a finite strip having holes and rigid fillers in it and the stress distribution in the joint is analyzed using a two-dimensional theory of elasticity. The effects of size and locations of rigid fillers and circular holes on the stress distributions at the interface and around the fillers and holes are clarified by numerical calculations. For verification, photoelastic experiments are performed using an epoxide resin plate modeled as an adhesive in the joint. The analytical results are in fairly good agreement with the experimental ones. In addition, the stress singularity at the edge of the interface is discussed.
