In-plane elastic wave propagation in the presence of a damaged interface is investigated.
The damage is modeled as a distribution of small cracks and this is transformed into a spring …

The method of wave function expansion is adopted to study the three dimensional scattering
of a time-harmonic plane progressive sound field obliquely incident upon a multi-layered …

Propagation of guided acoustic waves in infinite functionally graded piezoelectric plates is
considered. In contrast to commonly used discretization of a continuous through-plate …

A reliable non-destructive test to assess the integrity of double-cased wells is still an open
task. In the present work, we introduce an analytical–numerical formulation for modelling the …

The possibility is studied of applying spring boundary conditions to describe propagation of
elastic waves in layered composites with nonperfect contact of components or in the …

An analytic-numerical method to simulate the interaction of ultrasonic guided waves with
nonuniform interfacial imperfections in elastic multi-layered structures is presented. The …

We propose a deep learning (DL) regression strategy to solve inverse acoustic scattering
problems. This strategy is capable of recovering heterogeneous defect fields in any interface …

In adhesively bonded metallic structures, the oxide layer is a primary component of the micro-
composite layer at the adhesive/adherend interface whose morphology plays a critical role …

Laser ultrasonics has been investigated for inspecting the quality of a nuclear radiation
protection structure. A possibility is proposed to improve the signal to noise ratio (SNR) of a …

We propose an innovative deep learning (DL) regression strategy combined with guided
wave modes to address inverse acoustic scattering problems effectively. This approach …
