Project is aimed on study of new methods of nonlinear acoustic spectroscopy and their application for defectoscopy of concrete elements. In terms of project will be fulfilment:Theoretic analysis of nonlinear acoustic spectroscopy methods in light of their complication, application and serviceability for diagnostics of concrete elements.Make-up single blocks of gauging arrangement from moderate resources.Production of test blocks (concrete cubes and beams).Experimental checking of gauging arrangement.Gradual degradation of set specimen and their testing with nonlinear acoustic spectroscopy methods.Fulfilment of destructive and non-destructive examinations for verification of nonlinear ultrasonic spectroscopy methods.Analysis of result.Project is oriented on utilize knowledge of nonlinear effects rising at diffusion ultrasonic waves in unyielding matters. Records will be utilized for non-destructive testing of concrete elements. (en)
