"The article is focused on new methods of nonlinear ultrasonic spectroscopy for detection of structure integrity damage in building material usage. There were analysed undamaged specimens and also specimens containing defects of cracks type. Dynamic material response of samples with damaged material integrity was demonstrated by formation of new frequency components in the response frequency spectra." . "3"^^ . .
