Abstract
The change in the velocity of elastic waves caused by an applied uni-axial stress have been measured for two steels (ASTM A533B and A471). A novel tensile specimen, permitting the accurate measurement of absolute velocity, was designed and used for measuring the change in velocity of longitudinal and two orthogonally polarized shear waves for applied stresses ranging near to the yield point. Also measured was the velocity of Rayleigh surface waves, propagating in the large surface of a plate specimen of A533B steel. The variation of this surface wave velocity as a function of the angle, θ, between the propagation and the applied plate extensional stress directions was determined over the range 0° ≤ θ ≤ 90°. In all experiments, contact transducers were employed and the frequency ranged from 1.0 to 7.5 MHZ. The influence of these measurements on the quantification of internal residual stresses in solids is discussed.
