A finite volume element formulation for solution of elastic axisymmetric pressurized components

The authors have previously proposed the equivalent volume hypothesis (EVH) as part of integrity assessment of boiler tubes subjected to external erosion/corrosion. Currently, research is in progress at The University of New South Wales to develop and verify the EVH for tubes subjected to internal corrosion. This paper describes the formulation, verification and application of an axisymmetric and elastic finite volume element to internally corroded tubes. The initial computed results indicate that EVH is valid for these tubes. (C) 2000 Elsevier Science Ltd. All rights reserved.
