1104 異材接合体角部近傍における応力特性に関する研究  [in Japanese] A Study on the Stress Characteristic at a Vicinity of Vertex in Bonded Structure  [in Japanese]

In this study, the following were clarified : The order of singularity and displacement and stress characteristic at a vicinity of vertex in the three-dimensional bonded structure which combined isotropic material, orthotropic material and transverse isotropic material. The order of singularity is obtained by an eigenvalue analysis based on a finite element formulation. Concretely, Junction angle and junction direction changed, and the order of singularity was calculated. As the result, the relationship between the order and bonding condition was able to be clarified to some extent. And, it was possible to show tendency of the displacement and stress characteristic in the case in which the thermal distortion was considered and case in which it is not considered.
