In the present work, different types of acoustic emission (AE) sources are identified by
means of computational intelligence. The goal is to characterize the type of AE source and to …

The time reverse modeling (TRM) is applied for signal-based acoustic emission (AE)
analysis of reinforced concrete (RC) specimens. TRM uses signals obtained from physical …

An industrial lightweight concrete developed for pipe insulation is characterized using X-ray
computed tomography to determine the size distribution of air voids within the paste fraction …

In acoustic emission analysis, common source location algorithms assume, independently of
the nature of the propagation medium, a straight (shortest) wave path between the source …

Concrete material is a three-phase composite material. Its acoustic emission (AE)
characteristics are influenced by the properties of its components. The water-cement ratio …

This work presents a reverse-time imaging technique by cross-correlating the forward
wavefield with the reverse wavefield for the detection, localization, and sizing of defects in …

Time reverse modeling (TRM) is successfully applied to acoustic signals from a circular
microphone array, for mapping of sudden cracking sound events. Numerical feasibility using …

The paper aims to study the characteristics of the wave propagation paths in reinforced
concrete and to improve the existing velocity models. Therefore, coefficients of reflection and …

The acoustic emission (AE) technique can be used to locate failure-induced AE sources and
provides an alternative to continuously visualise the development of failures inside stressed …

Impact experiments on small-scale slabs made of concrete and aluminum were carried out.
Wave motion radiated from the epicenter of the impact was recorded as voltage signals by …
