Time reverse modeling of wave propagation in elastic media is applied to localize and
characterize acoustic emission using a numerical concrete model. The aim is to transform a …

We present a method based on the time difference of arrival (TDOA) and index minimal-error
subsets of microphones to localize sudden cracking sound events, which appear …

Modeling piezoelectric elements (piezos) using the finite element method with electro-
mechanical coupling requires significant computational resources. The electro-mechanical …
