    FE analyzing of layout types for multi-hole extrusion dies
    (Springer Int Publishing Ag, 2014) Bingöl, S.; Keskin, M. S.; Ayer, O.; Sarıkaya, K.; Burucu, O.; Alipur, P.
    Extrusion method is an important bulk-forming process to transform materials into semi-finished products in the form of bar, strip, and solid section as well as tubes and hollow sections. One of the basic considerations of die design is to determine the number of die openings based on the shape and size of the profile. In this study, variation of the extrusion load and temperature is investigated for different number and layout of die openings by finite element analysis. Three types of layouts, radial layout of a multi-hole die, flat layout of a multi-hole die and orientation of a shape around its center of gravity, were simulated with four openings in the dies. Moreover, the most commonly used type of them was also simulated for different number of openings in the die to compare the effect of the openings number on the extrusion.

    Finite element modeling of a torque rod forging process
    (Springer International Publishing Ag, 2014) Keskin, M. S.; Bingöl, S.; Elem, H. B.; Atar, A.
    Aluminum forging products has been increasingly used in automotive and aerospace industry due to their lightness and strength. Torque Rod is a connection part used for tying of the axle to the chassis frame. In this study, torque rod part from two different aluminum alloys (AA7075 and AA6061) were analyzed by finite element method. Three different initial temperatures of the workpiece; 300, 400 and 500 degrees C, have been used in simulations. Finally, the load-stroke and effective stress-stroke diagrams were examined according to forging of the mentioned aluminum alloys at different temperatures.
