摘要：
We propose an approach to the mathematical analysis of the crack resistance of steel of a main gas pipeline, which enables one to give quantitative estimates of the kinetics of dynamic fracture of the pipe with regard for the stochastic and cyclic nature of this process. It opens the possibility of modeling of the process of crack propagation in the pipe of a gas main and the analysis of separate stages of its growth. Special attention is given to the analysis of reliability of the proposed approach on the basis of comparison with the available data of full-scale experiments.
