Source locations provide fundamental information on earthquakes and lay the foundation for
seismic monitoring at all scales. Seismic source location as a classical inverse problem has …

Seismic anisotropy which is common in shale and fractured rocks will cause travel-time and
amplitude discrepancy in different propagation directions. For microseismic monitoring …

Concrete is a heterogeneous material with a disordered material morphology that strongly
governs the behaviour of the material. In this contribution, we present a computational tool …

Delaminations, cracks and other defects in engineered structures often lie close to the
theoretical resolution limit for ultrasonic waves. While ultrasonic waveform tomography has …

Experimental and numerical investigations have been performed to assess the feasibility of
damage detection around rebars in concrete using focused ultrasound and a Reverse Time …

In this work, the Acoustic Emissions (AEs), detected in real-scale Reinforced Concrete (RC)
beams which have been tested under four-point bending, are investigated and correlated …

The propagation properties of ultrasonic waves in rebar-reinforced concrete beams were
investigated and their ability for damage identification was demonstrated. Rectangular …

In the present work, an active source localization strategy is proposed. The presence of
active sources in a waveguide can have several reasons, such as crack initiation or internal …

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 …

Time reversal (TR) techniques due to their spatial and temporal focusing characteristics,
have been increasing applied in damage evaluation. Since probing waves strongly …
