Experimental Research of the Acoustic Emission (AE) Characteristics during the Tensile Process of the Blowout Preventer Shell Material

Abstract:

In this paper, The tesile damage process of the blowout preventor shell material ZG25GrNiMo was researched using acoustic emission technique. Analyzed the acoustic emission characteristics in different damage phases of this material using parameter analysis and waveform analysis. The result indicated that the acoustic emission characteristics are different in yielding, plastic deformation and rupture process. The differences of frequency spectrums of different damage modes are evident.
