The examination of the mortise and tenon joint by sheet-bulk metal forming

In this study, two sheets are joined perpendicular to one another by sheet bulk metal forming and are used for a variant of the traditional mortise-and-tenon joint. A sheet metal is called as a tenon, other sheet metal is called as a mortise. This method is known as the mortise and tenon jointsin the literature. There are many methods of connecting two sheets perpendicular to one other, such as welding, bolt-rivet, adhesive materials etc. In these methods, both the increasing cost and weight due to use intermediate materials are undesirable situation for the automotive industry. The advantages of mortise and tenon joints from other connection methods have been investigated and analysis have been performed. While these methods do not pose problems for the same materials, they can be problematic for two materials with different material properties. Aluminum-5182 and St12 steel materials were used as materials. Catia V5R20 was used as the design program. The mesh modelling was created for analysis via Hypermesh and than dynamic ekspilicit analysis was performed via Hypercrash. The four differences assembly folder were studied for analysis. The height of tenon and the geometric dimensions of mortise gap were used as geometric variables. In addition, the mortise gap was evaluated for both rectangular stepped holes and a stepless rectangular holes. The length variables of two tenons were used for rectangular stepless mortise, and in the same way, the length variables of two tenons were used for rectangular stepped mortise. The tenon lenghts are the same lengths for both mortise variables. Firstly tenon was pressed via upsetting in the perpendicular direction, and by the way tenon completely was filled the rectangular cavity of the mortise. According to compression tests, the stepless gap of mortie and tenon length of 10 mm piece was selected as the appripriate mortise and tenon joint parameters. After that tensile test analysis was prepared at the Hypercrash interface under specified boundary conditions. The tensile test was then applied to the finite element analysis output files. In order to find the appropriate study, both pressing and tensile test results were examined. According to these results, the stepless gap of mortie and tenon length of 10 mm piece was selected as the appripriate mortise and tenon joint parameters.
