Abstract

The FLANGE JOINTs are widely used in mechanical and aerospace structures. Hence, the static and dynamic behaviors of these joints are very important to be investigated. In the present study, a FLANGE JOINT is described using linear and torsional springs. The equivalent stiffness of these springs are theoretically obtained. In doing so, the edge of flange is modeled as a cantilever beam and its deformation under various loading is calculated. Then the nonlinear deformed curvature due to the enforced loading is obtained. Having the curvature, the joint stiffness is calculated separately for axial and lateral loadings. It has been observed that the equivalent linear and torsional springs have bilinear stiffness due to different behaviors in positive and negative loadings. An experimental setup consisting a single bolt FLANGE JOINT specimen has been designed to investigate the load-deflection behavior. The specimen puts into different loading configurations to obtain moment-rotation and force-deflection curves. A finite element model has been developed and result of the presented analytical model are compared with the experimental, FEM and previous numerical results. Finally, using the presented model, effect of changing the practical parameters of flange, like the bolt preload and flange thickness is investigated.
