| Outline of Final Research Achievements |
In this research, stress singularity evaluation methods of dissimilar joints were considered. It was shown that the formulations of stress singularity/concentration fields for piezoelectric materials and anisotropic materials were derived by similar form in the case of crack, cavity, inclusion and dissimilar joints problems. This study indicated that strength evaluation methods for piezoelectric materials can be performed based on similarities of analysis theory by experiments of elastic materials.
