Abstrakt:	The fundamental possibility of the adequate reproduction of the peculiarities of spall and shear fractures in studied shells with the required spatial resolution using methods of ultrasmall-angle and integral small-angle gamma tomography is demonstrated. The efficiency of such approaches and the comparison of the results of image reconstruction based on algorithms with data obtained using the method of small-angle gamma tomography performed by applying multiplicative algebraic algo-rithms and with photographs of meridian cross sections of recovered shells subjected to explosive loading are evaluated.
