Optical diffraction study of ultrasonic sound velocity in nitrous oxide and ammonia gases

Creator:

Strauch, Joseph George

Abstract:

The velocity of sound in gases was measured, using an ultrasonic wave train as a diffraction grating. The fundamental problems involved in the optical technique are discussed. An apparatus utilizing an objective lens of focal length 1.5 m and aperture f/20 was constructed and used at an ultrasonic frequency close...

A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

Creator:

Park, Heeyong

Abstract:

The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

Statistical design and analysis of sonic wave pressure treatment of wood

Creator:

Nair, Hari U.

Abstract:

Literature reports have indicated that application of sonic pressure waves enhances the rate of impregnation of preservatives in wood. However, these studies have been limited and inconclusive. The technique or process is not in commercial use. In this study a laboratory scale treating cylinder connected to a mechanical sonic wave...
