비틂홉킨슨봉을 이용한 알루미늄합금의 고속 전단변형 실험
High strain rate test of aluminum alloy with torsional Hopkinson bar
초록
The split Hopkinson bar technique is the most widely used method to study material behavior at high strain rate deformation. In the present paper, a torsional Hopkinson bar for testing thin-walled tube specimens at high strain rate is described. From the experiment of aluminum 6061, dynamic stress-strain relationship can be obtained and dynamic result is compared with static one.
