A Composite Grip Design for Elimination of Extraneous Noise During Acoustic Emission Testing
A major problem in acoustic emission analysis during dynamic loading is the noise generated by the test system itself. A composite grip assembly, designed on the principle of rapid attenuation of sound waves when they pass through multiple interfaces, can reduce the background noise by almost two orders of magnitude. This allows a maximum amount of information to be obtained through acoustic emission analysis.
