Computerized Tomography of Shock Field based on Acoustic Emission

The paper describes the measuring principle of(AE) firstly.Then the AE characteristics of an object under the action of a shock wave are studied.Furthermore,the computerized tomography technique of shock field,which is based on Kaiser effect,is brought forward.The paper also presentcs the flow chart and some key techniques,such as the techniques of preceding discrimination and discrimination the main form secondary,etc.The experimental result shows that the technique is practical as well as it can provides an effective means for the study of the object internal dislocation formation and slip mechanism.Finally,some problems need to be solved in the future are discussed.
