Abstract [en]

A new concept for impact-echo testing systems is developed in this workpackage, includinga new device, small and easy to handle, robust and unproblematic regarding transportation. The system utilizes advanced impact generation for fast scanning techniques and reproducible impacts. The data acquisition, filtering and visualization of data are optimized for the inspection of large structures obtaining data at many measurement points. Regarding the software state-of-the-art requirements were implemented for both, scientific applications and field-tests. A new feature is the semiautomatic estimation of crack parameters like crack depth. The main objective of the work done in this project was to provide a quick and reliable measurement method for the detection and characterization of vertical cracks in combination with the detection of delaminations, honeycombing etc. in concrete bridges.
