The authors proposed matrix representation of the phenomenological theory of the acoustoelastic effect based on the introduction of the speed matrices v/sub ik/ and of their relative variation /delta/v/sub ik/, the determination of the dependence of these quantities on the characteristics of the external effect, and the determination of the type of the coupling coefficients. The main coefficients are represented by the acoustoelastic coefficients of the speed /beta//sub ik/ of the uniaxial stress state. The multiaxial stress state is also described using these coefficients and is independent of the modeling assumptions. The resultant equation are used in the practice of acoustic strain gauging in nondestructive diagnostics of the stress-strain state of the inspected object and can also be used in developing mathematical facilities and apparatus system for acoustic tomography.
