Numerical study of the stress-strain state of the thermal insulating sections of a column of steam delivery pipes

  • 21 Accesses

Abstract

A procedure is suggested for a numerical study of the axisymmetrical thermoelastoplastic stresss-train state of sections of a column of steam delivery pipes based on modelling a section of a shell of rotation with a proportionally reduced number of corrugations and lengths of cylindrical sections. The procedure is developed within the scope of the KirchhoffLove hypothesis on the basis of equations of the theory of simple loading processes taking their history into account. The procedure is substantiated by comparing calculated results for the stressstrain state of sections with eight and four corrugations.
