Longitudinal Residual Stress Analysis in AA2024-T3 Friction Stir Welding
Friction Stir Welding (FSW) is an innovative solid-state joining process, which is gaining a great deal of attention in several applicative sectors. The opportune definition of process parameters, i.e. minimizing residual stresses, is crucial to improve joint reliability in terms of static and dynamic performance. Longitudinal residual stresses, induced by FSW in AA2024-T3 butt joints, have bee...
متن کاملFinite Element Studies on Friction Stir Welding Processes of Polyethylene Plates
One of the interesting state-of-the-art approaches to welding is the process of friction stir welding (FSW). In comparison with the fusion processes, FSW is an advantageous method as it is suitable for the non-fusion weldable alloys and polymeric materials joining. Regarding the materials pure solid state joining, it also provides joints with less distortion and enhanced mechanical properties. ...
متن کاملInfluence of Friction Stir Welding residual stresses on the mechanical behaviour of aluminium stiffened panels
In this work, the longitudinal residual stresses that arise from FSW processes were measured by means of the Contour Method. These residual stresses were then introduced into a numerical simulation model based on the Finite Element Method (FEM), and their effect on the buckling collapse load of aluminium stiffened panels was assessed. The sensitivity of the models to initial geometrical imperfe...
متن کاملFinite element analysis of stiffened plates
The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine frequencies, mode shapes and buckling loads of different stiffened panels. In structural modelling, the plate and the stiffener are treated as separate finite elements where the displacement compatibility transformation takes into account the torsion – flexural coupling in the s...
متن کاملFINITE ELEMENT SIMULATION OF HEAT TRANSFER IN FRICTION STIR WELDING OF AL 7050
Friction welding is widely used in various industries. In friction welding, heat is generated by conversion of mechanical energy into thermal energy at the interface the work pieces during pin rotation under pressure. A three-dimensional thermo mechanical simulation of friction stir welding (FSW) processes is carried out for Aluminium Alloys of 6061and 7050 where the simulation results are comp...
