This model improves the conventional CZM, taking into account the fiber-bridging phenomenon and the variation of the element size among the thickness in the curved zone. The advantages of the enhanced model are underlined when results obtained from the numerical simulations of a four-point-bending test in compliance with ASTM D6415 standard are compared with the corresponding experimental results. The prediction of the post-failure behavior obtained with this model is closer to that obtained experimentally than with the conventional model. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.8 2022 MATERIALS SCIENCE, CHARACTERIZATION & TESTING 10 / 32 = 0.312 2022 Q2 T1 MECHANICS 52 / 137 = 0.38 2022 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 201 / 343 = 0.586 2022 Q3 T2 MATERIALS SCIENCE, COMPOSITES 17 / 28 = 0.607 2022 Q3 T2 0.669 2022 Civil and Structural Engineering 2022 Q2 Materials Science (miscellaneous) 2022 Q2 Mechanics of Materials 2022 Q2 Mechanical Engineering 2022 Q2 Mathematics (miscellaneous) 2022 Q2 5.1 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Cuartero, Jesús Universidad de Zaragoza (orcid)0000-0002-6100-7412 Castejon, Luis Universidad de Zaragoza (orcid)0000-0002-9007-1560 Miralbes, Ramón Universidad de Zaragoza (orcid)0000-0002-9702-9314 Valladares, David Universidad de Zaragoza (orcid)0000-0002-6046-4558 5004 530 Universidad de Zaragoza Dpto.
