Some problems of material boundaries and structure influence on destruction mechanisms

By Morozova Tatiana Mikhailovna


Subject of inquiry: pipe-lines and apparatuses in oil production and petroleum industries. The aim of the work is to develop models of destruction that may be observed in pipe-lines service within hydrogen sulphide-carrying media. A model of formation of distruction structures in low-carbon low-alloyed pipe steels, when performing their hydrogenation, has been offered based on the solution of problems of theory of elasticity. Conditions for forming two structures of destruction have been determined allowing to connect critical conditions, as far as hydrogen and mechanical loads are concerned, not only with a crack geometry but also with structural irregularity of the pipe-line material and parameters of its strength anisotropyAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
