Element finite Method models have occasionally supplemented experimental methods, to investigate such operational fails. In this approach we explore technical options to comprehensively understand crack propagations, by first, evaluating the Stress Intensity Factor using ANSYS Parametric design language then, comparing with the Displacement Correlation Technique, for an elliptical base gas piping (20″APL Gr. B) suffering a longitudinal welding-induced crack, under a compression of 1.86 MPa. The value for an Electric Resistance Welding crack was calculated for the two-dimensional plane, for a quarter-length of propagated crack along the elliptical front. The value estimates are 0.94x MPa from ANSYS Parametric design language vs. 0.7 MPa from DCT the two methods are close less than 1. These results were compared with the theorical stress intensity factor for elliptical cracks by Broek1 David called elementary engineering fracture mechanics where the values were 0.5x MPa. We found that the proposed FEM method for estimating is the approach that is closest to the theoretical value. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.59 2023 Mechanics of Materials 2023 Q2 Mechanical Engineering 2023 Q2 3.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Bea, Jose Antonio Universidad de Zaragoza (orcid)0000-0002-9417-2705 Chakraborty, Sourojeet Galatro, Daniela 5004 605 Universidad de Zaragoza Dpto.
