Impact-Echo for the evaluation of concrete structures, In : Non-destructive evaluation of reinforced concrete structures, Volume 2: Non-destructive testing methods

This chapter describes the impact echo non-destructive test method. After a summary of the history of the development of the method, the basic physical phenomena underlying the method are presented. Then data analysis approaches and signal processing techniques, including time and frequency domain processing, are described. A description of the needed equipment and classical measurement configurations are reviewed. Finally classical applications of the impact echo method are summarized.
