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.
