"The ultrasonics methods, which detect applied or residual stress in materials, are based on nonlinear interaction of a small dynamic disturbance (acoustic waves) with the pre-formed state of the solid. This weak phenomenon (acoustoelasticity) leads to a dependence of acoustic wave velocities on initial stress, and a stress-induced anisotropy in the acousticalproperties of the material." .
