Description

During the past five years, there has been a resurgence of activity in the area of stress measurement by ultrasonic techniques because new methods of accounting for texture effects have been developed {1}. In fact recent review article by Sayers {2} outlines several different ways of separating stress and texture effects so that each can now be measured separately and the information used for a variety of practical applications. The work described in this paper is aimed at using shear horizontal (SH) waves to measure the thermal stresses developed in railroad tracks during the usual day/night temperature cycle {3}. To accomplish this, a hand held probe that can operate on the web or base of the rail was fabricated and procedures that minimize sources of error were developed.

Application of Surface Skimming SH Waves to Stress and Texture Measurement in Steel
