Experimental study on wire breakage detection by acoustic emission

Limin SUN, Ji QIAN

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4, Pages 503-509 doi: 10.1007/s11709-011-0132-8

Abstract: This paper experimentally investigated wire breakage detection in a steel cable by acoustic emissionthe attenuation laws of waveform amplitudes were discussed based on stress wave propagation in the wire, which was generated by kNocking and wire breakage.Compared with the other source, the wire breakage source contained a much higher energy, and thus, thewire breakage signal can be distinguished from the other source by comparing the non-attenuation energy
