Modelling of process of the autofastening of thick-walled pipes

Article is devoted to modeling of process of an autofastening of a thick-walled pipe by loading of its preparation by the internal hydraulic pressure causing plastic deformations. An essential lack of the developed earlier theoretical bases applied to calculation of durability of the autofastened pipes is that they don't consider possible change of the intense deformed state after preparation machining. The method of calculation of process of an autofastening which considers the subsequent machining of preparation of a pipe is developed.
