A closed-form expression is developed to define the stiffness of the cohesive layer. A novel procedure that allows the use of coarser meshes of decohesion elements in large-scale computations is proposed. The procedure ensures that the energy dissipated by the fracture process is correctly computed. It is shown that coarse-meshed models defined using the approach proposed here yield the same results as the models with finer meshes normally used in the simulation of fracture processes" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "National Aeronautics and Space Administration" , "dc.relation.ispartof": "© NASA TM Technical Reports, 2005, núm. 213547" , "dc.relation.ispartofseries": "Articles publicats (D-EMCI)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Mecànica de fractura" , "dc.subject": "Fracture mechanics" , "dc.subject": "Materials compostos -- Mètodes de simulació" , "dc.subject": "Composite materials -- Simulation methods" , "dc.subject": "Materials compostos -- Fatiga" , "dc.subject": "Composite materials -- Fatigue" , "dc.subject": "Materials compostos -- Deslaminatge" , "dc.subject": "Composite materials -- Delamination" , "dc.title": "An Engineering Solution for using Coarse Meshes in the Simulation of Delamination with Cohesive Zone Models" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.idgrec": "008228" }
