Building Spectral Element Dynamic Matrices Using Finite Element Models of Waveguide Slices and Elastodynamic Equations

Shock and Vibration, 2013
Structural spectral elements are formulated using the analytical solution of the applicable elastodynamic equations and, therefore, mesh refinement is not needed to analyze high frequency behavior provided the elastodynamic equations used remain valid ...

FEM to

HBRC Journal, 2013
Finite element modeling (FEM) is considered a famous method belonging to the numerical simulation methods. First it is a dominant technique in structural mechanics. Hence, this paper is focused on the effect of feed rate (f) on surface roughness (Ra) and cutting force components (Fc,Ft) during the face-milling operation of the titanium alloy (Ti–6Al–4V)

Analyzing the Total Structural Intensity in Beams Using a Homodyne Laser Doppler Vibrometer

Shock and Vibration, 2000
The total structural intensity in beams can be considered as composed of three types of waves: bending, longitudinal, and torsional. In passive and active control applications, it is useful to separate each of these components in order to evaluate their ...

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

Advanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.
