Mathematical Modeling

The reliability indicators calculation for the pipeline systems with crack-like defects and complicated service conditions

Abstract: The existing methods for pipeline systems reliability estimation, based on a normative approach, do not consider in an explicit form neither time as a factor, nor the probability nature of characteristics of load-carrying ability and loads that often leads to designation of unfairly high values for stress reserve factors. Methods based on probability approaches allow excluding these shortcomings, however, in spite of the fact that they are rather widely theoreti-cally justified, their practical applications do not exceed 1 %. In this paper the algorithms and methods for pipeline systems reliability indicators calculation for practical application which allow determining the values during design or service stage are presented. These methods are based on the theory of classical statistics.

Keywords: pipeline, crack-like defects, method of interpolation polynomials, not-canonical decomposition, stress intensity factor, statistical dynamics problem, reliability function
