Abstract

Recently, bonded structure is used for many machine parts and electronic components. But, it may cause stress concentration near the corners. This leads to a decrease in strength, and reliability is lost. Therefore, it is necessary to evaluate the stress characteristics at a vicinity of vertex in bonded structures. There is stress singularity parameter to evaluate the stress characteristics. The stress state of a junction interface can be known by analyzing this singularity parameter. In this paper, stress characteristics in the junction interface of anisotropic bonded structures are analyzed by finite element method. As a result, the influence that the joint angle gave to the stress characteristic is clarified.
