| dc.description.abstract | 본 논문에서는, 고 변형률 속도에서의 알루미늄 합금의 압축 변형거동을 홉킨슨 압력봉 시험, SHPB 방법을 통해 연구하였다. 이와 함께 음향방출기법이 사용되었고, 웨이브 가이드선을 통해 시편에 연결된 AE 센서를 이용하여 충격 변형시 검출되는 AE 신호를 실시간으로 검출하였다. 검출된 AE 신호를 통해 진폭, 에너지 및 최대 주파수 특성을 분석하였다. 또한 손상 기구에 따른 음향방출신호의 특성을 분석하기 위하여 시험 수행 후 충돌 시험편 표면과 측면을 관찰하였다. 변형률이 높아질수록 AE 진폭과 AE 누적에너지는 증가하였고, AE 최대 주파수는 감소하였다. 각 신호의 특성은 재료의 손상 기구와 밀접한 관련이 있는 것으로 확인되었다. | - |
| dc.description.abstract | In this study, the compressive deformation behaviors of aluminum alloy under high strain rates were investigated by means of a SHPB test. An acoustic emission (AE) technique was also employed to monitor the signals detected from the deformation during the entire impact by using an AE sensor connected to the specimen with a waveguide in real time. AE signals were analyzed in terms of AE amplitude, AE energy and peak frequency. The impacted specimen surface and side area were observed after the test to identify the particular features in the AE signal corresponding to the specific types of damage mechanisms. As the strain increased, the AE amplitude and AE energy increased whereas the AE peak frequency decreased. It was elucidated that each AE signal was closely associated with the specific damage mechanism in the material. | - |
