Description

In the development of acoustoelasticity as a tool for the nondestructive evaluation of active and residual stresses, it has become clear that the anisotropy of the materials under examination plays a significant role in the ultimate utility of the method [1, 2]. This technique is based on the observation that the speeds at which various waves propagate through a material depend not only on the elastic stiffness, but also on the amount of deformation or stress to which the material is subjected. If a material’s elastic and acoustoelastic constants are known, and if sufficiently precise measurements of velocity are made, the stress may be evaluated.
