Forging is a metal forming process which involves non-linear deformations. Finite element and finite volume software programs are commonly used to simulate the process. In these simulations, material properties are required. However, stress-strain relations of the materials at some elevated temperatures are not available in the material libraries of the related software programs. In this study, the stress-strain curves have been obtained by applying the Cook and Larke Simple Compression Test to AISI 1045 steel at several temperatures on a forging press with a capacity of 1000 tons. The stress-strain curves have also been determined by simulating the processes in a commercial finite element software. It is observed that experimental results are consistent with the numerical ones. A modular die set has been designed and manufactured to conduct the Cook and Larke Simple Compression Test. It has been shown that the forging press with data acquisition system can be used as a material testing equipment to obtain stress-strain curves.

Analysis of warm forging process
Aktakka, Gülgün; Darendeliler, Haluk; Department of Mechanical Engineering (2006)
Forging is a metal forming process commonly used in industry. Forging process is strongly affected by the process temperature. In hot forging process, a wide range of materials can be used and even complex geometries can be formed. However in cold forging, only low carbon steels as ferrous material with simple geometries can be forged and high capacity forging machinery is required. Warm forging compromise the advantages and disadvantages of hot and cold forging processes. In warm forging process, a product...
Analysis of roll-forging process
Karacaovalı, Hakan; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2005)
Roll-forging is a metal forming process and mainly used for preform forging of long parts prior to press or hammer forging in the industry. Variable cross sections through the length of billet can be obtained by roll-forging to acquire an adequate distribution of material to the next forging stages. In the design of process and dies used in roll-forging, there are some empirical techniques in literature. However these techniques only provide approximate reduction ratio and elongation during the process and ...
Finite element analysis of bending operation of aluminum profiles
Penekli, Ufuk; Darendeliler, Haluk; Department of Mechanical Engineering (2008)
Bending process is an important forming process in most industrial fields. Springback and cross-section distortion are commonly faced problems in bending process. Springback behavior of closed and open section beams changes with different parameters such as cross-section type, cross-section dimensions, bend radius and bend angle. For closed sections like tube, the dominating problem is cross-section distortion. The thickness of the tube at intrados (inner surface of tube being in contact with die) increases...
Analysis of coining process in production of medallion
Akkuş, Derya; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2009)
Coins and medallions are manufactured by using coining process which is a metal forming process. In coining of medallions, there is a strong need to shorten the production time and reduce the production cost and waste of material in conventional coining method. An alternative coining method may be considered in order to reduce the production time and the manufacturing cost. In this study, a new method has been proposed. In the proposed method, design of the medallion is performed by utilizing computer aided...
Numerical analysis of ablation process on a two dimensional external surface
Aykan, Fatma Serap; Dursunkaya, Zafer; Department of Mechanical Engineering (2005)
The thermal response analysis of an ablative material on a two dimensional external surface is performed. The method is applied to both rectangular and cylindrical coordinate systems, where rectangular coordinate system is used for comparison with results available in literature. The current study solves the decomposition of the material at high temperatures by using the nth order Arrhenius equation but excludes the removal of char from the surface due to mechanical erosion or phase change and considers tha...
