마그네슘 합금 판재용 인장-압축 시험기 개발

다국어 초록 (Multilingual Abstract)

Recently, application of magnesium alloy sheets to automotive industry has been rapidly increasing. However, the application is still challenging due to the inferior formability, which should be overcome by proper design of forming process. Therefore, reliable experimental data to be used for the complex material models for the optimization of forming process with magnesium alloys are essential. In this paper, a new cyclic load tester, which can measure the stress-strain curves of thin sheet metals under non-monotonous condition such as tension/compression or compression/tension, was developed. Especially, the new cyclic loading tester has a direct heating system being heated up to 400℃, thus the stress-strain curves under various level of temperature can be measured. Preliminary test results are demonstrated for the commercially available magnesium alloy sheet. But more investigations are necessary to improve the current feature of the tester.
