Simulation Methods for Guided Wave-Based Structural Health Monitoring: A Review
TL;DR: The state-of-the-art in numerical wave propagation analysis on guided wave-based structural health monitoring (SHM) applications is reviewed, and various numerical methods are discussed and assessed with respect to their capability of simulating guided wave propagation phenomena.
Journal ArticleDOI
Dynamic finite element analysis of axially vibrating nonlocal rods
TL;DR: In this article, a frequency-dependent dynamic finite element method is developed to obtain the forced vibration response of damped non-local rods, and the stiffness and mass matrices of the nonlocal rods are also obtained using the conventional finite element methods.
Journal ArticleDOI
Hybrid local FEM/global LISA modeling of damped guided wave propagation in complex composite structures
Yanfeng Shen,Carlos E. S. Cesnik +1 more
TL;DR: In this article, the authors present a new hybrid modeling technique for the efficient simulation of guided wave generation, propagation, and interaction with damage in complex composite structures, which allows the accurate modeling of the local dynamics of the transducers and keeping the LISA formulation in an explicit format, which facilitates its readiness for parallel computing.
Journal ArticleDOI
Application of scanning laser Doppler vibrometry for delamination detection in composite structures
TL;DR: In this article, the authors used the Spectral Element Method (SEM) with a piezoelectric transducer for delamination detection in composite structures, in which a mesh was composed of 3D spectral elements.

Accuracy in modeling the acoustic wave equation with Chebyshev spectral finite elements
Walter Dauksher,Ashley F. Emery +1 more
TL;DR: A quantitative study of dispersion in Chebyshev spectral finite element solutions to the one-and two-dimensional scalar wave equations is presented in this paper, where the spectral elements employ central time differencing and three mass matrix treatments: consistent, row-summed and diagonal-scaled.
