Introduction
Acoustic Emission Testing or AET is an effective no destructive test technique utilized for stress monitoring and material analysis based on detecting acoustic emissions caused by internal structural variations. Applied in many industries such as aerospace, oil & gas, energy, automotive, and construction, AET finds use in the determination of incipient faults, structural monitoring in real time, and assurance of safety.
