Simultsonic: A Simulation Tool for Ultrasonic Inspection
TL;DR: In this paper, a simulation program SIMULTSONIC is developed at CNDE to help determine and/or help optimize ultrasonic probe locations for inspection of complex components, such as very thin-walled pipes.
Journal ArticleDOI
An experimental study on the behavior of Ao mode transduced using misaligned air-coupled transducers in composite laminates
TL;DR: In this article, the amplitude variation in amplitude of the fundamental anti-symmetric Lamb mode (A o ) when misalignments were purposefully introduced in the air-coupled probes.
Proceedings ArticleDOI

TL;DR: In this article, an experimental method to visualize the propagation of ultrasonic Lamb waves in composite plates with delaminations, using air coupled ultrasonic transducers, is described, using this method experiments are done, on glass fiber reinforced plastic(GFRP) laminates, to study the Lamb wave interactions with delamination type defects.
Journal Article
Elastic Wave Sensing Using Fiber Bragg Grating-Based Sensors and Dynamic Interrogators
TL;DR: In this paper, the use of fiber Bragg gratings (FBGs) as a viable alternative to conventional piezo electric transducers is discussed, and the directional response of FBG-based sensors is discussed.
Proceedings ArticleDOI
Shm of orthotropic plates through an ultrasonic guided wave stmr array patch
TL;DR: In this article, a flexible Printed Circuit Board (PCB) based patch was developed for SHM of aluminum and composite plates, which can provide a means for the in-situ measurement of changes in the elastic moduli during the life time monitoring of structures.
