Acoustical methods in non-destructive testing of concrete: Review of foreign works in theoretical researches

This paper is devoted to the review and analysis of foreign publications in the field of acoustic methods in theoretical studies of problems of nondestructive testing as applied to the analysis of the physical properties of concretes. Methods that combine theoretical and experimental approaches are considered in the introduction and deterministic and stochastic methods are analyzed independently. The application of the finite and boundaryelement methods is then described and a new method forstudying the considered problems is proposed.
