Journal ArticleDOI
A semi-analytical finite element formulation for modeling stress wave propagation in axisymmetric damped waveguides
TL;DR: In this paper, a semi-analytical finite element (SAFE) method is presented for analyzing the wave propagation in viscoelastic axisymmetric waveguides.
Journal ArticleDOI
Stress measurement and defect detection in steel strands by guided stress waves
TL;DR: In this paper, a simplified acoustoelastic formulation of the Pochhammer-Chree vibrations in cylindrical waveguides is derived in the framework of the partial wave representation for guided waves.
Journal ArticleDOI
Semi-Supervised Multiresolution Classification Using Adaptive Graph Filtering With Application to Indirect Bridge Structural Health Monitoring
Siheng Chen,Fernando Cerda,Piervincenzo Rizzo,Jacobo Bielak,James H. Garrett,Jelena Kovacevic +5 more
TL;DR: A multiresolution framework to deal with nonstationarities in the signals and extract features in each localized time-frequency region and semi-supervised learning to train on both labeled and unlabeled signals is proposed.
Journal ArticleDOI
Acoustic emission monitoring of CFRP reinforced concrete slabs
TL;DR: In this article, an acoustic emission (AE) study performed during laboratory tests of concrete slab specimens strengthened with carbon fiber reinforced polymer (CFRP) strips is demonstrated, and an algorithm to classify the cracks in concrete, the disbond of the CFRP strips from the soffit of the slab, and the eventual failure (debonding or concrete shear).
Journal ArticleDOI
Propagation of ultrasonic guided waves in lap-shear adhesive joints: case of incident a0 Lamb wave.
TL;DR: In this article, the authors studied the propagation of ultrasonic guided waves in adhesively bonded lap-shear joints and showed that the dispersive behavior of the guided wave in the multilayer overlap is highly dependent on bond state.
