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.deBetonconcreteEFITelastodynamic finite integration techniquemodelingModellierungultrasound620658670Ultraschallmodellierung mit dem EFIT-Code zur zerstörungsfreien Prüfung an Beton und isotropen SchweißnähtenModeling the ultrasonic inspection of concrete and austenitic weldsconference paper
