Friction Stir Welding (FSW) is a solid-state welding technique that involves the joining of metals without filler materials. A cylindrical rotating tool plunges into a rigidly clamped workpiece and moves along the joint to be welded.
Submodeling is a finite element technique that allow users to obtain more accurate stress and strain results in a particular region of a model which is a small area of concern in comparison to whole model.
The wear damage is one of the crucial factors of wheel damage in the rail industry. In this project, some material has been added to a wheel with a pre-defined thickness and the amount of residual stresses were investigated. This part was done with ANSYS and an APDL code was generated.
In this project, an algorithm has been written with use of Mechanical APDL to eliminate the elements which carry the least loads in each optimization stage. After some killing steps, the model would get the lightest weight with the same load capacity as the whole model.
In this project, a single-point mechanism was theoretically designed and checked its functionality in MSC.ADAMS in order to damp the wind forces in several directions.
