Ultrasonic Measurement Of Elastic Constants Of Composites
Yoseph Bar-Cohen,Ajit Mal +1 more
TL;DR: In this article, the authors describe an ultrasonic testing system that yields data on elastic constants of matrix/fiber laminated composite material, which is performed nondestructive and involves access by ultrasonic probes to only one side of material specimen.
Book ChapterDOI
Interaction of Lamb Waves with Defects in a Semi-Infinite Plate
TL;DR: In this paper, a pitch-catch technique was used to detect material loss and thickness reduction in a plate-like structure, which can be used for non-destructive inspection of aircraft.
Proceedings ArticleDOI
Laser Doppler velocimetry and PZT sensing for the study of guided waves in a stepped aluminum plate
TL;DR: In this paper, a 10 mm PZT was used for Lamb wave propagation in a metal plate with a downward step and the responses were measured at multiple locations, along a line crossing the step, using a scanning laser Doppler vibrometer (LDV).
Proceedings ArticleDOI
Guided wave ultrasound field mapping using a network of removable bragg grating transducers
TL;DR: In this paper, an ultrasound field mapping method, using fiber Bragg gratings embedded in a flexible, removable sheet that can be reused over different structures, has been implemented.
Proceedings ArticleDOI
Guided acoustic emission waves in a thick composite plate
Ajit Mal,Sauvik Banerjee +1 more
TL;DR: In this paper, an efficient and accurate semi-analytical method based on the wavenumber integral representation of the elastodynamic field is described to calculate the surface responses produced by localized dynamic loads in a relatively thick composite plate.
