3D nurbs-enhanced finite element method
Sevilla Cárdenas, Rubén; Fernández Méndez, Sonia; Huerta, Antonio (2009-06-08T10:12:04Z)
Text en actes de congrés
Accés obertAn improvement of the classical finite element method is proposed in [1], the NURBS-Enhanced Finite Element Method (NEFEM). It is able to exactly represent the geometry by means of the usual CAD description of the boundary ... -
3D NURBS-enhanced finite element method (NEFEM)
Sevilla Cárdenas, Rubén; Fernández Méndez, Sonia; Huerta, Antonio (Wiley and Sons, 2011-10-14)
Article
Accés restringit per política de l'editorialThis paper presents the extension of the recently proposed NURBS-enhanced finite element method (NEFEM) to 3D domains. NEFEM is able to exactly represent the geometry of the computational domain by means of its CAD boundary ... -
A C0 interior penalty Finite Element Method for flexoelectricity
Ventura, Jordi; Codony Gisbert, David; Fernández Méndez, Sonia (2021-09)
Article
Accés obertWe propose a C0 Interior Penalty Method (C0-IPM) for the computational modelling of flexoelectricity, with application also to strain gradient elasticity, as a simplified case. Standard high-order C0 finite element ... -
A combined XFEM phase-field computational model for crack growth without remeshing
Muixí Ballonga, Alba; Marco Alacid, Onofre; Rodríguez Ferran, Antonio; Fernández Méndez, Sonia (Springer, 2020-10-07)
Article
Accés obertThis paper presents an adaptive strategy for phase-field simulations with transition to fracture. The phase-field equations are solved only in small subdomains around crack tips to determine propagation, while an XFEM ... -
A comparison of two formulations to blend finite elements and mesh-free methods
Huerta, Antonio; Fernández Méndez, Sonia; Liu, W K (2004-03)
Article
Accés obertMesh-free methods have since their early developments been blended to the finite element formulation in order to benefit from the advantages of both numerical techniques. In this paper, two recently proposed formulations ... -
A Cº interior penalty method for 4th order PDEs
Fojo, Dani; Codony Gisbert, David; Fernández Méndez, Sonia (2020-12-01)
Article
Accés obertA method to solve 4th-order PDEs using the Finite Element Method (FEM) with standard C0 elements is derived and studied. It is based on a special weak form accounting for the discontinuous derivatives of the approximation ... -
A finite element method solution to the phase-field model of the Stefan problem
Orteu, Max; Sala Lardies, Esther; Fernández Méndez, Sonia (2022-12-20)
Article
Accés obertThis work is concerned with the Phase-Field model of the Stefan problem, as well as the numerical solution with the Finite Element Method to simulate examples in two dimensions. -
A hybridizable discontinuous Galerkin phase-field model for brittle fracture
Muixí Ballonga, Alba; Fernández Méndez, Sonia; Rodríguez Ferran, Antonio (2019-05-01)
Article
Accés obertPhase-field models for brittle fracture consider smeared representations of cracks, which are described by a continuous field that varies abruptly in the transition zone between unbroken and broken states. Computationally, ... -
A hybridizable discontinuous Galerkin phase-field model for brittle fracture with adaptive refinement
Muixí Ballonga, Alba; Rodríguez Ferran, Antonio; Fernández Méndez, Sonia (John Wiley & sons, 2020-03-30)
Article
Accés obertIn this paper, we propose an adaptive refinement strategy for phase-field models of brittle fracture, which is based on a novel hybridizable discontinuous Galerkin (HDG) formulation of the problem. The adaptive procedure ... -
