The nonlinear nature of contacts has consistently posed a significant challenge in Finite Element Analysis, requiring nonlinear solutions to accurately describe the static and dynamic behavior of structures. This project aims to investigate contact linearization models by examining various configurations of fasteners on bolted plates, the most common type of mechanical joint in industrial applications. Linear analysis offers numerous advantages, including reduced computational costs and, above all, the ability to implement solutions provided by the MSC Nastran solver, widely used in the Aerospace & Defense field. The study initially focuses on static and dynamic analyses of discretization methods for two bolted plates.
