Impact echo testing procedure
The impact-echomethod is based on the measurement of acoustic waves. These waves are actively generated by a short mechanical impact, typically with a small metal sphere (impactor, see 1.2) at the component surface close to a detection sensor. The waves propagate into the component and are reflected at … Zobacz więcej The impact-echo methodis mainly used in solid masonry construction for thickness measurement of components accessible from a single side. Particularly in tunnel construction, it is used to check the thickness of the … Zobacz więcej The non destructive technology impact echo was developed in the 1980’s by National Institute of Standards and Technology and Cornell University. In early days, this technique was characterized by … Zobacz więcej Witryna1 mar 2007 · To circumvent this, a new procedure was developed by applying an imaging procedure to the impact-echo data, as stack imaging of spectral amplitudes based on impact-echo (SIBIE) [2,3].
