Structural magnetic and magnetostrictive properties of Tb0.3Dy0.7−xNdxFe1.93 [x = 0, 0.05, 0.1, 0.15 and 0.2] compounds
S. Narayana Jammalamadaka,S. Narayana Jammalamadaka,G. Markandeyulu,Krishnan Balasubramaniam,J. Arout Chelvane +4 more
TL;DR: In this article, the results pertinent to structural, magnetic, magnetostrictive studies of the Tb 0.3 Dy 0.6 Nd 0.1 Fe 1.2 compound were reported.
Journal ArticleDOI
Finite Difference Time Domain Simulation of Ultrasonic Phased Array Sector Scan for Imaging Cracks in Large Pipes, Elbows, and Tee Sections
TL;DR: In this paper, the authors used the sector scan feature of a phased array transducer to image and size crack-like defects in large pipes, elbows, and tee sections.
Journal ArticleDOI
Ultrasonic interferometric sensor for rheological changes of fluids
TL;DR: In this paper, an ultrasonic interferometric sensor has been introduced for the measurement of subtle changes in the physical properties of fluids such as density, viscosity, and bulk modulus.
Book ChapterDOI
Guided Plate Wave Potential for Damage Analysis of Composite Materials
TL;DR: In this paper, the physics of wave propagation within the thin composite structures was fully explored using experimental methods and was backed by a very strong theoretical basis in order to obtain NDE guidelines for fiber reinforced composite materials.
Journal ArticleDOI
Characterization of Deep Sub-wavelength Sized Horizontal Cracks Using Holey-Structured Metamaterials
Mohamed Subair Syed Akbar Ali,Kiran Kumar Amireddy,Krishnan Balasubramaniam,Prabhu Rajagopal +3 more
TL;DR: In this paper, an experimental demonstration of deep sub-wavelength resolution in the ultrasonic regime using a metamaterial lens is presented, where the successful transmission of the decaying evanescent waves which contain much larger wave vectors than the propagating waves enables to overcome the diffraction limit set by the operating wavelength.
