Abstract
This paper presents stress analysis including geometrically nonlinear effect using the finite element method for S5400-narutal rubber bonded structures. In case of large deformation problems for two dimensional model, the Green-Lagrange strain is generally employed. In this study, at first we compared the difference solutions obtained between small and large deformations using a cantilever beam model. Subsequently, the stress analysis for the SS400-natural rubber bonded structures using the delamination force obtained from delamination test was carried out. Delamination test was carried out for SS400 and natural rubber single lap joint by changing the adhesive width. Finally, the intensity of stress singularity obtained from large deformation analysis were evaluated in case of several computational models by changing the adhesive width.
