Acoustic Emission refers to the phenomenon where transient elastic waves are generated by the rapid release of energy from localized sources within a material. This can occur during processes such as deformation, crack formation, or other structural changes. The emitted sound waves can be detected and analyzed to monitor the integrity of materials and structures. In engineering and materials science, Acoustic Emission is used as a non-destructive testing technique. By capturing and interpreting these sound waves, engineers can identify potential failures or weaknesses in structures like bridges, pipelines, and pressure vessels, ensuring safety and reliability in various applications.
