In this paper, defect detection and identification in aluminium joints is investigated based on
guided wave monitoring. Guided wave testing is first performed on the selected damage …

The eigenvalue scheme proposed by Zhong and Williams in 1995 is a well-conditioned and
efficient approach to solve the wave propagation characteristics of periodic structures …

Although the wave finite-element method (WFEM) is an efficient numerical technique to
analyze wave propagation characteristics and forced response of waveguides at medium …

A numerical approach is proposed to localize defects in elastic waveguides connected by
curved elastic joints. 2D assemblies involving straight waveguides with a curved joint and a …

The reliable estimation of the wavenumber space (k-space) of the plates remains a long-
term concern for acoustic modeling and structural dynamic behavior characterization. Most …

We propose and demonstrate a fiber surface plasmon resonance (SPR) curvature sensor
with the function of directional recognition by coating a metal film on one side of the fiber. By …

Guided elastic waves, propagating through curved waveguides, have attracted significant
attention in the recent past, both from the perspectives of assessment of structural integrity …

Generally, the high-fidelity finite element models of aero-engines comprise millions of
degrees of freedom (DOFs). Although they can provide precise predictions of structural …

A wave finite element (WFE) strategy to predict and localize defects in networks of straight
pipes with curved joints is proposed. This involves estimating the times of flight taken by …

This thesis investigates defect detection and localization in waveguide assemblies,
exploring the interaction between waves in straight waveguides with curved joints and …
