Impact detection and acoustic emission data processing
A method and apparatus for processing measurements of an acoustic wave, the acoustic wave being within a member (12) made of a composite material and caused by an impact to the member (12), the method comprising: analysing the measurements to detect an initial acoustic wave feature; analysing the measurements to detect the presence of further acoustic wave features, the further features occurring after the initial feature; if there are no further acoustic wave features, determining that the impact to the member (12) has not changed the structure of the member (12); if there are further features, determining a value of a function of the further acoustic wave features; if the determined value satisfies certain criteria, determining that the impact has changed the structure of the member (12); and if the determined value does not satisfy the criteria, determining that the impact has not changed the structure of the member (12). By doing so, impact induced damage is detected and quantified by processing separately acoustic data generated by the impact from acoustic data generated by acoustic emission due to damage generation..
