926 Elastic/Elastic-Plastic Analyses on Free-Edge Stress Singularity of Bonded Dissimilar Materials with an Interlayer

Abstract

In this study, stress distributions on the interface of bonded dissimilar materials with an interlayer were calculated by using the elastic/elastic-plastic finite element method to investigate the effect of the interlayer on the free-edge stress singularity. It was found that the free-edge stress singularity varied with applied load in the elastic-plastic case. Stress distribution near the intersection of the interface and free-surface was controlled by the free edge stress singularity of the bonded dissimilar materials without interlayer as in the case of elastic analysis.
