The macrodescription of the wave fields in elastic 3D composite structures with multiple disk-shaped thin elastic inclusions of low contrast and random orientation has been realized. On the basis of the analytical-numerical relations obtained the conclusions (important for practice) as to regularities of the processes of wave formation in the considered composites have been made. The detected dynamic effects are to be considered both at designing the composites with given properties and at predicting their prefracture state. Product Description popup.authors Бутрак І.О.
