Ultraschallmodellierung mit dem EFIT-Code zur zerstörungsfreien Prüfung an Beton und isotropen Schweißnähten
Other Title
Modeling the ultrasonic inspection of concrete and austenitic welds
Abstract
The Power of EFIT (Elastocynamic Finite Integrations Technique) is demonstrated on two typical NDT-Problems: the inspection of austenitic welds having a columnar grainsturcture and the wall thickness measurement of concrete bars. In the first part the pulse echo inspection of a austenitic weld with columnargrains parallel to the surface and a slot (surface breaking crack) in one weld flank is shown. In the second part the sound propagation (80 khz) through a thick concrete bar including air bubbels is presented.
