The corresponding relationship between mechanical behavior of 30CrMo steel material and acoustic emission signal was studied by using dynamic acoustic emission signal in this paper. Through the analysis of the parameters of amplitude, ringing count, and duration of acoustic emission signals, we obtained the dynamic acoustic emission characteristics of the specimen during elastic deformation, plastic yielding, hardening, necking, and fracture, which reflect the structural behavior changes in the stretching process. The results of the experiment showed that it was instructive to use acoustic emission signal parameters to study the damage test of the material and the online monitoring of the engineering structural material.
