Journal ArticleDOI
Vibration based Structural Health Monitoring of a composite T-beam
TL;DR: In this article, a force-vibration set-up, including a laser vibrometer system, is employed to measure the dynamic behaviour of the T-beam and the Modal Strain Energy Damage Index algorithm is applied using the bending and torsion modes.
Journal ArticleDOI
Delamination detection with fibre Bragg gratings based on dynamic behaviour
TL;DR: In this paper, the influence of delamination on the resonance frequencies of carbon-PEI laminated cantilever beams was investigated using embedded fibre Bragg grating strain sensors.
Journal ArticleDOI
Determining the von Mises stress power spectral density for frequency domain fatigue analysis including out-of-phase stress components
TL;DR: In this article, a new formula was proposed to take into account phase differences in the determination of an equivalent von Mises stress power spectral density (PSD) from multiple random inputs.
Journal ArticleDOI
Acoustic-based damage detection method
TL;DR: In this article, a noncontact, acoustic-based damage detection method is proposed and tested with an objective that the proposed method is able to detect the location and extend of damage accurately.
Journal ArticleDOI
Performance of several viscothermal acoustic finite elements
TL;DR: In this paper, a finite element for viscothermal acoustics, which can be used to model such devices, is presented, and several different FEM discretizations are studied on a 2D thin gap problem.
