Numerical simulation of elastic wave propagation in masonry compared with acoustic emission experimental results

Tijdschriftbijdrage - Tijdschriftartikel

It has been shown in acoustic emission literature that the distance between a possible cracking event and a receiver is affectingthe signal parameters providing a wrong image of the real fracture characteristics. In this study, lab-scale experimentaltests on masonry components are performed in order to determine the disturbance of the acoustic emission wave propertiesand verify the experimental observations via numerical wave propagation analysis. The investigation is extended to differentgeometries including “couplets,” “triplets” and masonry walls. The simulations allow to understand, verify and predictthe acoustic emission signal properties alterations in many different types of masonry experiments as well as the correctcharacterization of the fracture mode.
