The strength сalculation of energy systems pipelines with bends by finite element method

Abstract

In this article the tube system classification, destination and structure analysis were discussed. The decision of applied problems with using the numerical methods is based by reducing this problem to a finite-dimensional. Finite element method and ANSYS complex were used to calculate stress concentration.As the construction loses its stability at first, then it loses strength, therefore, the determination of the absolute value of the critical load is an important problem in the design of pipelines.All elements of hydrotechnical facilities and pipelines that are loaded by external pressure or inner pressure of which is much small are require the verification calculation of the the loss of stability.As a result of numerical experiment for rectilinear steel pipeofrelatively infinite length, was obtained the dependence of critical external pressure, under action of which the construction loses stability, from the thickness of wall.
