(Elsevier Ltd, 2019)In this paper, the recently proposed linearly consistent one point integration rule for the meshfree methods is extended to arbitrary polytopes. The salient feature of the proposed technique is that it requires only one ...
-
(Elsevier, 2020)In this work, we present an eXtended Geometry Independent Field approximaTion (X-GIFT) formulation for cracked Kirchhoff-Love plates. The plate geometry is modeled by Non-Uniform Rational B-Splines (NURBS) while the solution ...
-
(Elsevier, 2020)In this work, the isogeometric collocation (IGA-C) is paired with two types of enrichment: Plane Wave (PW-) and Generalized Harmonic Polynomial (GHP-) functions, to solve 2D-problems for the Helmholtz equation. A parametric ...
-
(Royal Soc, 2015)In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of ...
-
(Elsevier, 2017)In this study, a new and efficient computational approach based on isogeometric analysis (IGA) and refined plate theory (RPT) is proposed for the geometrically nonlinear analysis of functionally graded (FG) microplates. ...
-
(Elsevier Ltd, 2019)© 2019 Elsevier Ltd In this work, we demonstrate the application of PHT-splines for time-harmonic acoustic problems, modeled by the Helmholtz equation. Solutions of the Helmholtz equation have two features: global oscillations ...
-
(Universidad de Chile, 2016)Las correas transportadoras son los equipos más utilizados a nivel industrial para el transporte de material, por presentar una alta eficiencia energética, una estructura más bien simple y una buena adaptación a las ...
-
(Universidad de Chile, 2014)Los Elastómeros Electro-Sensibles son materiales que se caracterizan por sufrir grandes deformaciones en presencia de un campo eléctrico. Debido a esto la atención de los científicos se ha centrado en estudiar el comportamiento ...
-
(Elsevier, 2017)In this paper we tackle the simulation of microstructured materials modelled as heterogeneous Cosserat media with both perfect and imperfect interfaces. We formulate a boundary value problem for an inclusion of one plane ...
-
(Elsevier, 2020)Piezo-electric energy harvesters (PEHs) are widely used to recycle waste vibrations for pow-ering small electronic devices. In this work, the performance of PEHs of non-conventional shapes is studied with the aim to optimize ...
-
(Universidad de Chile, 2015)Este trabajo consiste en obtener el campo de deformación de una probeta de acero SAE 1020 sometida a flexión, a partir de mediciones del campo de desplazamiento a través de correlación de imágenes digitales con cámaras DIC ...
-
(SAGE Publications, 2014)In this paper, we use the weight function for an elliptical crack embedded in an infinite elastic media in conjunction with the alternating method to derive the exact analytical solution for the stress intensity factor ...
-
(Elsevier, 2018)In this paper, a new approach is developed for structural shape optimization, which consists in coupling the particle swarm optimization (PSO) algorithm and the isogeometric boundary element method (IGA-BEM). The IGA-BEM ...
-
(Elsevier Ltd, 2019)In this study, the vibration behaviours of functionally graded microplates with cracks are investigated by means of a simple yet rigorous version of Mindlin's generialised continuum and the extended isogeometric analysis ...
-
(Wiley-V C H Verlag GMBH, 2016)In this paper we prove the existence of weak solutions for the inclusion problem in anti-plane Cosserat elasticity in Sobolev space setting, and for the corresponding systems of boundary integral equations.
-
(Wiley, 2018-06)This paper presents an approach to generalize the concept of isogeometric analysis by allowing different spaces for the parameterization of the computational domain and for the approximation of the solution field. The ...
