Sound Source Location Error Analysis of Acoustic Emission Technique for Thick-Wall Pressure Vessel

厚壁压力容器声发射技术声源定位误差分析

Acoustic emission is the characteristic and irreversible sound emitted by a material when it is deformed.

声发射是当材料变形时所发出的特殊的不可逆的声响.

The characteristics of sound emission technique, and the testing and theoretical basis for the inspection of fatigue fracture are introduced in this paper.
