چکیده
The problems of vibrations structural elements still remain demanded due to the widespread use polymeric and composite materials also necessity consideration a damage factor. Mathe¬ma¬tical difficulty many-dimensional led emergence one-dimensional theories, approximately taking into account non-unidimensionality movement.
