AE Characteristic under Tensile of Polyethylene for Low Pressure Pipe
저압배관용 폴리에틸렌의 인장시험시 발생한 음향방출 특성
Abstract
This study is to look at the effect for deformation of Polyethylene, on the wave forms produced by tensile test. Signals collected were then classified visually into three types according to their shapes in the time and frequency domain. Each type should contain signals which could be correlated to a certain micro failure mechanism that occurs during the tensile process. The result showed that the acoustic emission method could be effectively used for analysis of fracture mechanism in Polyethylene structures.
