Özet
In this paper, the constitutive equation parameters (Johnson-Cook parameters) of the 33MnCrB5 material were determined with the help of tensile tests. Initially, Johnson-Cook (JC) model was used for performing the simulations of the sample with finite element analysis with the help of ANSYS software. For these operations, the sample was first used at a certain temperature (24 degrees C) and low strain rates (10(-1), 10(-2), 10(-3) s(-1)) and quasi-static tensile tests were performed. Then, high temperature tensile tests were performed with strain rate values of 10(-3) s(-1) at temperatures of 300 degrees C, 600 degrees C, and 900 degrees C, respectively. Finally, JC parameters belonging to test materials were found in accordance with the results obtained from the high temperature tensile and quasi-static tests. In the last stage, the results obtained from the simulation software for the yield stress, maximum stress, and elongation values were compared with the experimental results. As a result, deviation values for quasi-static tests are calculated as 5.04% at yield stress, 5.57% at maximum stress, and 5.68% at elongation, while for high temperature, yield stress is 9.42%, maximum stress is 11.49% and the elongation value is 7.63%. The accuracy of JC parameters was verified with the comparison made with the obtained data.
