Experimental-theoretical study of the mechanical behavior of polymer composite construction when developing a method of reliable detection of defects by microfocus radiography

In this paper, a method of mechanical impact on an element of a ring frame of a U-shaped cross-section with the aim of opening a closed delamination to a minimum size is considered, which will allow this defect to be detected by the nondestructive X-ray diffraction method, in condition that the loading will not lead to the formation of new defects and further growth of the existing ones.
