An Abstract of Friction-Stir Riveting:Characteristics of Friction-Stir Riveted Joints and MechanicalTesting by Yuan Hu Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Masters of Science Degree in Mechanical Engineering The University of Toledo May 2015 In automobiles fields, material weight is very important, so in order to reduce the weight, a lot of light metals are used more and more frequently in the automobile industry, such as aluminum and magnesium alloys. But in large-scale applications, there are some difficulties in welding them. In this situation, new joining methods are needed and developed, for example friction-stir welding and self-piercing riveting. The University of Toledo has developed a new joining method called hybrid friction-stir riveting. This method can be used to join both similar and dissimilar metals. This kind of joint is created by spinning and pressing a solid rivet into layers of sheet metals. It has the characteristics of both friction-stir welding and self-piercing riveting. In this process, sheet metals are jointed by rivet and a cohesion zone near the steel rivet through the stirring process. The joining strength comes from the mechanical interlocking, adhesion, and solid bonding. The joint quality is affected by tooling, joining process and the geometry of the rivet. For example, the rivet should provide as much interlocking to the sheets as possible, meanwhile, its concave area should be filled with the mixed aluminum materials. In the experiment, spindle speed and feed rate were found affect the joint quality. These effects are discussed through both experimental and numerical ways. A best choice of the joint geometry was performed and experimentally verified.
