ELASTOPLASTIC STRESS STATE OF CYLINDRICAL PIPE UNDER INTERNAL PRESSURE

Abstract
The paper deals with calculating the plane axisymmetric elastic-plastic stress state of a heavy wall steel pipe under the uniform internal pressure. Two limiting states are applied to the pipe: elastic and plastic resistance of material for two values of the pressure limit. At the intermediate pressure, the cross-section of the pipe consists of two concentric annular zones, namely the inner the outer elastoplastic zones. Exhaustion of the load-bearing pipe capacity occurs when the elastoplastic deformation generated by the inner pipe surface reaches its outer surface. Therefore, the presence of the elastic deformation zone on external pipe surface does not lead to the structural failure.
