Influence of Friction Stir Welding residual stresses on the mechanical behaviour of aluminium stiffened panels
نویسندگان
چکیده
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 imperfections was also analysed.

Residual Stresses in Friction Stir Welding
Friction stir welding is an innovative joining process being developed for use in aerospace manufacturing. Like most welding processes there exist problems with post-weld residual stresses and subsequent geometrical distortion. The residual stress-state of a welded component can be modified using suitably applied mechanical tensioning and thus distortion can be reduced or eliminated. In the pre...
متن کاملGlobal mechanical tensioning for the management of residual stresses in welds
The general principles behind the global mechanical tensioning technique for controlling weld residual stresses are examined using a finite lement model to follow their evolution throughout the welding process. While we focus specifically on friction stir welding, the tool is represented imply as a heat source. As a result, the findings have relevance to a wide range of welding processes. For a...

متن کاملNumerical simulation of transient temperature and residual stresses in friction stir welding of 304L stainless steel
Three-dimensional nonlinear thermal and thermo-mechanical numerical simulations are conducted for the friction stir welding (FSW) of 304L stainless steel. The finite element analysis code—WELDSIM, developed by the authors specifically for welding simulation, was used. Two welding cases with tool rotational speeds of 300 and 500 rpm are analyzed. The objective is to study the variation of transi...
