In many machine parts and electronic parts, junction of dissimilar material which utilized the properties is carried out. But, the concentration of stress is generated in the bonded interface. This causes the deterioration of strength, and reliability is lost. There is stress analysis for three-dimensional bonded structures by finite element analysis based on eigenvalue problem as an example of computational mechanics approach method of this problem. But when analyzing by this method, unstable distribution is appeared in the boundary part. In this study, to improve the calculation accuracy, try to increase the degree of element used for the analysis. And the improvement of accuracy was confirmed by some analytical models.
