    • Decay of solutions in nonsimple thermoelastic bars 

      Fernández-Sare, Hugo; Muñoz Rivera, Jaime E.; Quintanilla de Latorre, Ramón (2010-11-01)
      Article
      Accés restringit per política de l'editorial
      In this paper we investigate the asymptotic behavior of the semigroup associated to the solutions of the initial boundary value problem for a one-dimensional nonsimple thermoelastic solids. We show that the semigroup is ...

    • Finite volume for stress analysis upon polygonal, unstructured and non conforming meshes 

      Cardoso Nungaray, Víctor; Botello Rionda, Salvador; Zárate Araiza, José Francisco; Oñate Ibáñez de Navarra, Eugenio (2019-01)
      Article
      Accés obert
      Within 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 

      Leseduarte Milán, María Carme; Quintanilla de Latorre, Ramón; Racke, Reinhard (2016-11)
      Report de recerca
      Accés obert
      We 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 obert
      We 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 

      Liu, Zhuangyi; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (Wiley-VCH, 2016-07-01)
      Article
      Accés obert
      In 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 ...

    • Topological sensitivity analysis in heterogeneous anisotropic elasticity problem: theoretical and computational aspects 

      Giusti, Sebastian Miguel; Ferrer Ferré, Àlex; Oliver Olivella, Xavier (2016-11)
      Article
      Accés obert
      The 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 ...

    • Una metodología numérica de malla para la resolucion de las ecuaciones de elasticidad mediante el método de puntos finitos 

      Perazzo Maggi, Franco Orlando; Miquel Canet, Juan; Oñate Ibáñez de Navarra, Eugenio (International Centre for Numerical Methods in Engineering (CIMNE), 2003)
      Llibre
      Accés obert
      El objetivo principal de esta monografia es obtener y desarrollar la formulacion del Método de Puntos Finitos, como método totalmente libre de malla, para la resolución de las ecuaciones de la elasticidad en solidos. Para ...
