Analysis of fracture characteristic of a gas main pipe on the basis of the additive mathematical model of the cyclic random process and polynomial functionThe use of a mathematical model to describe the phenomenon of dynamic fracture of the gas main in a broad range of crack propagation rates is substantiated, taking into account the stochastic and cyclic nature of this process....
Parametric identification of cam system mathematical model hardly determinable invariables for gas main sectionsThe identification problem solubility of such hardly d eterminable physical parameters for the gas main section m athematical model as the distribution averaged along the pipeline friction coefficient, and the true mean lengthways pipeline temperature when using the isothermic...
Structural degradation of the welded joint of the gas main after a long-term operation in sub-acid soilThe authors investigated the main regularities in the structural and mechanical degradation of steel and a welded joint of the "Soyuz" gas main in operation....
