Abstract

For the purpose of improving water-tightness and durability of sealed joint, the cross-sectional shape of sealed joints to reduce the stress-concentration at the adhesive part of substrate were proposed, and their fatigue resistance was evaluated by fatigue testing machine. The parameters of test specimen were the cross-sectional shapes and the adhesion types of sealed joints. Also, before carrying out the tensile test and the joint movement cyclic test, the stress condition into the cross section of sealed joint was analyzed by finite element method. As a FEM results, the maximum principal compression of rectangle joint was higher than concave joints. Also, in tensile and fatigue test results, when occurring adhesion loss on the substrate, the fatigue resistance of sealed joint decreased extremely. However, when there is adhesion loss on the substrate, the sealed joint with concave cross-section had higher fatigue resistance than that of rectangle shape.
