접착 조인트의 본드층내 변형률 분포 고찰

초록

The strain distribution of the bond layer has been compared with the experimental data and analyzed according to the different mesh refinements and different types of element. The mesh density was changed along the longitudinal direction of adherend, the longitudinal direction of overlapped region and the vertical direction of adhesive. In addition, the effect of the different types of element was evaluated using soild, shell, continuum shell and plane strain element. The geometric nonlinear analysis was performed to consider the larger deformation of the joint.
