| A rivet is a cylindrical rod (shank) with a tapered tail and a head. Rivets are used in many design applications such as joining together two or more plates. The full understanding of these joints is essential in many areas, e.g. automobile and aviation industries and marine applications, mainly for leak proof joints like oil tanks, boilers etc. However, the riveted joints studies have been so far poorly comprehended and necessitate more research. The aim of this research is to establish and analyze 3D computational models of single riveted joints based on elastic-plastic properties. The static stress under bending/shearing and squeezing forces of rivet material with PA25 alloy (AlCu4Mg) according to EN 1301-2:1997 ductile fracture conditions were analyzed for residual tensional load and airflow in the riveted connection by the finite element method. This paper proposes a hybrid simulated analysis of bending/shearing and squeezing forces combined simultaneously for riveting process. In addition to this, the external loading and airflow simulations were also carried out to find residual stress solutions. The effects of riveting operation parameters i.e. material type, head die design, impact force, and geometric parameters under BSSF of plates for rivets were investigated under airflow conditions. The ANSYS explicit finite element analysis of riveting process was realistic approach to simulate hundreds of rivets before the riveted joint system realization to prevent service and work safety hazardous. |
