Technology Definition

Acoustic Emission Testing (AET) is a non-destructive testing method used to monitor and evaluate materials and structures by detecting the release of transient elastic waves, known as acoustic emissions, which occur when a material undergoes deformation or damage. This technique involves the placement of sensors on the surface of the material, which capture the high-frequency waves generated by the sudden redistribution of stress within the material, such as from crack formation or growth.

AET is widely used in various industries, including aerospace, civil engineering, and manufacturing, to identify defects like cracks, leaks, or corrosion in real-time, allowing for early detection and assessment of structural integrity without causing damage to the object being tested. The method is valued for its ability to provide continuous monitoring and detect the location and severity of defects by analyzing the characteristics of the emitted waves.
