Acoustic Emission Testing (AET) is a non-destructive testing method used to monitor the integrity of materials and structures. It involves detecting and analyzing high-frequency sound waves generated by the rapid release of energy within a material, often due to stress, cracks, or other defects. This technique is valuable in various industries, including aerospace, construction, and manufacturing. During AET, sensors are placed on the surface of the material being tested. These sensors capture the sound waves, which are then analyzed to identify the location and severity of any issues. This method allows for real-time monitoring and can help prevent catastrophic failures by identifying problems before they escalate.
