Parametric Studies on the Effect of Four Types of Fastener Modeling in Channel Type Tension Fitting

In this paper, some parametric studies on four types of Channel type tension fitting’s fasteners’ stiffness modeling is presented. Tension fittings are commonly classified into five types. They are Bathtub fitting, Channel fitting, Angle fitting, ‘PI’ fitting and Double angle fitting. Tension fittings are conservatively sized as their weight is usually small relative to their importance. In the previous studies, the channel fitting was considered to be fixed at all the fastener locations. Thus, the results obtained were conservative because the load was getting reacted at the first line of fasteners only. In order to study the effect of fastener’s flexibility and hence the load flow inside the tension fitting two methods (Tate & Swift) of fastener modeling were employed in the previous study. It observed that, the flexible boundary condition allow for a better load flow into the channel fitting as compared to the fixed boundary condition. In this study, fastener flexibility with two more methods (Grumann and Huth) is performed on the distribution of internal stresses in the channel fitting as compared to the fixed boundary conditions. Also comparison of previous results (Tate and Swift) is made with Grumann and Huth methods of modeling of fastener. Aluminum alloy 7050T7452 is selected for the study.
