Abstract
The Method of Real Elements (MeReEl) is a novel procedure for the assessmen t of the integrity of components containing defects. The method uses a defo rmation based failure criterion, and replaces the structure with an equival ent rod system for which a database of experimental load-displacement curve s has been created. To illustrate the procedure, MeReEl is used to estimate the limiting load for a tube with a circumferential defect under combined bending and tension. Reserve factors for the section are estimated for a re presentative set of defects. Capabilities and limitations on the use of MeR eEl are discussed. (C) 2000 Elsevier Science Ltd.
