The monitored components or materials send out the sound waves because of the stress deformation and structure deformation or local weak collapse, and the acoustic emission technique is used to sample and dispose those waves to comprehend the internal force, damaged degree of the target component or material, through sound waves that sent out by the monitored slave computer, and combined with the engineering practice, we can achieve safety assessment, risk prediction, nondestructive testing and other purposes.
These defects and damages will send out the weak acoustic signals when receive other external forces or external influences, and the essence of those singals is the local energy instantaneous release of the defect position inside the target material, its intensity and frequency changes are closely linked with internal materials.
Subsequently, Canada, the Soviet Union, Japan and other countries have begun to study the acoustic emission instrument, and in the 1960s and 1970s, acoustic emission technique gradually used widely in dam safety monitoring, geological safety testing, materials testing and security assessment.
