Crack Detection in Armor Plates Using Ultrasonic Techniques (PREPRINT)
Autor: Gregory Smith, Michelle Charbeneau, Mary Bienkowski, Thomas J. Meitzler, Ivan Wong, Euijung Sohn, Allen H. Meitzler
A method of using piezoelectric lead zirconate titanate (PZT) transducers to characterize the vibrational modes of Vehicle Body Armor Support System (VBASS) plates and its preliminary results are presented. The amplitude of the vibrational modes of u

Poisson's ratio for polycrystalline silicon used in disk-shaped microresonators
Autor: Allen H, Meitzler
Publikováno v: IEEE transactions on ultrasonics, ferroelectrics, and frequency control. 53(2)
Integrated circuit technology has been used to fabricate miniature disk resonators of polycrystalline silicon that operate at frequencies above 100 MHz. The ratios of low-order resonant frequencies in these resonators can be used to determine the val

Ultrasonic wave interferometers
Autor: Edward N. Sickafus, Allen H. Meitzler
Publikováno v: The Journal of the Acoustical Society of America. 97:2624-2624
An acoustic or ultrasonic device includes two ultrasonic energy transmission paths having substantially identical transmission characteristics for a neutral condition of the device. One or both of the transmission paths include path altering structur

Unusual microstructures in TiO2ceramic pellets with asymmetrical electrical conductivity
Autor: W. T. Donlon, Allen H. Meitzler, Samuel S. Shinozaki
Publikováno v: Journal of Applied Physics. 53:7290-7298
Ceramic pellets of TiO2 (rutile), with embedded Pt wire electrodes, have been heat treated in a manner that changed the normal electrical properties of rutile at room temperature from those of an insulator to those of a semiconductor with rectifying
