Non-Destructive Techniques (NDT)
Within the research lines, the GTS works on signal processing for nondestructive testing, both for the detection and for the characterization of damage in cementitious materials. Among all the different non-destructive essays, the group activity is mainly focused in the processing of: ultrasonic signals (conventional and air coupled), impact-eco signals, georadar signals, acoustic signals and laser-ultrasonic signals. The developed signal processing algorithms are employed in multiple applications: material characterization, damage location, tomographic reconstruction, acoustic localization ...
The GTS collaborates with the ICITECH (Institute of Science and Technology of the Concrete) for the characterization of different types of global damage in cementitious materials using sonic and ultrasonic signals. For this porpoise wide frequency analytical algorithms combined with signal modality features extraction are employed.
