Computing upper and lower bounds for the J-integral in two-dimensional linear elasticity
(2006-01)
Article
Accés obertWe present an a posteriori method for computing rigorous upper and lower bounds for the J-integral in two-dimensional linear elasticity. The J-integral, which is typically expressed as a contour integral, is recast as a ... -
Finite volume for stress analysis upon polygonal, unstructured and non conforming meshes
(2019-01)
Article
Accés obertWithin this paper we discuss a numerical strategy to solve the elasticity problem upon unstructured and non conforming meshes, allowing all kinds of flat-faced elements (polygons in 2D and polyhedra in 3D). The core of the ... -
On (non-)exponential decay in generalized thermoelasticity with two temperatures
(2016-11)
Report de recerca
Accés obertWe study solutions for the one-dimensional problem of the Green-Lindsay and the Lord-Shulman theories with two temperatures. First, existence and uniqueness of weakly regular solutions are obtained. Second, we prove the ... -

Article
Accés obertWe study solutions for the one-dimensional problem of the Green-Lindsay and the Lord-Shulman theories with two temperatures. First, existence and uniqueness of weakly regular solutions are obtained. Second, we prove the ... -
On the time decay of solutions for non-simple elasticity with voids
(Wiley-VCH, 2016-07-01)
Article
Accés obertIn this work we consider the non-simple theory of elastic material with voids and we investigate how the coupling of these two aspects of the material affects the behavior of the solutions. We analyze only two kind of ... -
Rayleigh wave correction for the BEM analysis of two-dimensional elastodynamic problems in a half-space
(Wiley and Sons, 2004-08)
Article
Accés obertA simple, elegant approach is proposed to correct the error introduced by the truncation of the infinite boundary in the BEM modelling of two-dimensional wave propagation problems in elastic half-spaces. The proposed method ... -
The computation of bounds for linear-functional outputs of weak solutions to the two-dimensional elasticity equations
(2006-01)
Article
Accés obertWe present a method for the computation of upper and lower bounds for linear-functional outputs of the exact solutions to the two dimensional elasticity equations. The method can be regarded as a generalization of the well ... -
The efficient computation of bounds for functionals of finite element solutions in large strain elasticity
(2002-09)
Article
Accés obertWe present an implicit a posteriori finite element procedure to compute bounds for functional outputs of finite element solutions in large strain elasticity. The method proposed relies on the existence of a potential energy ... -
Topological sensitivity analysis in heterogeneous anisotropic elasticity problem: theoretical and computational aspects
(2016-11)
Article
Accés obertThe topological sensitivity analysis for the heterogeneous and anisotropic elasticity problem in two-dimensions is performed in this work. The main result of the paper is an analytical closed-form of the topological ... -
