Description

In a previous conference we presented a comparison of several different acoustic techniques to estimate residual stresses in complex situations.1 Of the several methods, the use of the attenuation of broad band pulses appeared to be better than the usual method of inferring strain from changes in the propagation velocity. The measurement of strain through changes in the velocity is effected through the equations 1 ΔV/V = f(εij), 2 Δt/t=Δd/d−ΔV/V where εij = strain tensor, t = time for the wave to traverse the specimen, d = specimen thickness, V = wave velocity.

The Use of Acoustic Signal Attenuation in the Examination of Residual Strains: Part B — The Use of Experimentally Derived Acoustic Strain Correlations in the Evaluation of Residual Strains and Stresses
