Expresiones explícitas de los autovectores ortonormalizados para materiales transversalmente isótropos en el formalismo de Stroh. Aplicación al análisis de singularidades en uniones adhesivas [Presentation]
(AEMAC (asociación española de materiales compuestos), 2003)
La resolución de problemas de elasticidad lineal anisótropa, utilizando el formalismo de Stroh, se basa en el conocimiento de los autovalores y autovectores de la matriz de elasticidad fundamental N. En el presente trabajo ...
Boundary Element Analysis of Three-Dimensional Exponentially Graded Isotropic Elastic Solids [Article]
(Tech Science Press, 2007)
A numerical implementation of the Somigliana identity in displacements for the solution of 3D elastic problems in exponentially graded isotropic solids is presented. An expression for the fundamental solution in ...
Symmetric Variational Formulation of BIE for Domain Decomposition Problems in Elasticity – An SGBEM Approach for Nonconforming Discretizations of Curved Interfaces [Article]
(Tech Science Press, 2007)
An original approach to solve domain decomposition problems by the symmetric Galerkin boundary element method is developed. The approach, based on a new variational principle for such problems, yields a fully ...
Modelo de interfase elástica lineal frágil (MIELF) aplicado a problemas tridimensionales con crecimiento de grietas en modo mixto [Article]
(Grupo Español de Fractura, 2016-03)
En la actualidad, desde un punto de vista numérico, la mayoría de investigaciones sobre los despegues y/o delaminaciones que aparecen en las interfases se centran en modelos 2D. Para modelar el comportamiento no lineal ...
Recent developments in the evaluation of the 3D fundamental solution and its derivatives for transversely isotropic elastic materials [Article]
(2012)
Explicit closed-form real-variable expressions of a fundamental solution and its derivatives for three-dimensional problems in transversely linear elastic isotropic solids are presented. The expressions of the fundamental ...
Green's Function Evaluation for Three Dimensional Exponentially Graded Elasticity [Article]
(Wiley, 2008)
The numerical implementation of the Green's function for an isotropic exponentially graded three dimensional elastic solid is reported. The formulas for the nonsingular `grading term' in this Green's function, originally ...
Numerical study of the inter-fibre failure under biaxial loads [Article]
(Elsevier, 2011)
The inter-fibre/matrix failure under transverse tension has already been the object of several micromechanical studies by the authors, for single fibre case or dilute packing. These studies have made it possible to understand ...
Micromechanical aspects of the inter-fibre failure in fibrous composite materials under bi-dimensional loads [Presentation]
(European Society for Composite Materials, 2004)
Many criteria have historically been proposed to predict failures in composites. Some of them were quasimimetically taken from metallic materials failure criteria and others were inspired by observation of the appearance ...
Modeling of interface cracks in a composite with a fibre bundle under biaxial transverse loads [Article]
(Grupo Español de Fractura, 2013)
En el presente trabajo se presenta un estudio numérico, donde se caracteriza el inicio y crecimiento de los despegues producidos en las interfases entre fibra y matriz en un material compuesto sometido a cargas transversales ...
Caracterización del daño de acuerdo a la mecánica de la fractura en laminados 0/90 [Article]
(Grupo Español de Fractura, 2004)
Los laminados 0/90 de materiales compuestos fibrosos cuando son sometidos a carga en la dirección de las fibras a cero grados, presentan un daño consistente en la aparición de grietas transversales en las láminas a 90 ...
