Considering the characteristics of roll-forming, springback and microstructure changes during the welding process, the longitudinal residual stresses (LRS) of cold-formed square hollow sections (CFSHS) in the roll-forming and high-energy welding processes was simulated with finite element method. It is concluded that LRS of CFSHS at the outer and inner surfaces are basically equal in value and opposite...
The key technologies at which the computer simulation of welding process aims include meshing model, applying loads as well as handling molten pool. A transitional mesh division is proposed to establish the finite element model to solve the contradiction between the calculation accuracy and the computing time; With the application of the multiple load step, the functional relationship between the...
The calculations of the temperature fields, the residual stress distributions and the displacement distributions of welding process by using three-dimensional thermo-elastic-plastic FEM (finite element method) are time-consuming. Some high efficiency computational methods aiming at characteristics of welding process in welding process numerical simulation were proposed such as segmented moving heat...
