Abstract: A simple procedure for calculating primary stress consistent with the ASME B&PV Code is presented. The procedure is based on an iterative elastic analysis technique referred to as the elastic ...

Abstract: This paper describes how optimal shapes for axisymmetric pressure vessels can be established based on maximizing limit pressure. This type of problem has been rarely examined in the literature ...

Abstract: The redistribution of stress in a linear, thin shell model of a curved pipe creeping under the action of a constant applied in-plane bending moment is represented by an equation of evolution ...

Abstract: This paper presents an analysis for the in-plane bending behavior of smooth thin pipe bends connected to tangent pipes or rigid flanges under steady-state creep conditions. Creep flexibility ...

Abstract: In this paper, a simple method for calculating lower-bound limit loads for shells is presented, based on Ilyushin’s and Ivanov’s generalized yield criterion, respectively, and using the elastic ...

Abstract: A method for bounding limit loads by an iterative elastic continuum finite element analysis procedure, referred to as the elastic compensation method, is proposed. A number of sample problems ...

Abstract: A simple approach for calculating upper-bound shakedown loads is described. The method is based on a series of iterative elastic finite element analyses (the elastic compensation procedure) applied ...
