Stabilization of low-order cross-grid $\mathbf{ P_k Q_l}$ mixed finite elements
(Elsevier Science, 2018-03)
In this paper we analyze a low-order family of mixed finite element methods for the numerical solution of the Stokes problem and a second order elliptic problem, in two space dimensions. In these schemes, the pressure is ...
A Finite Element Stress Analysis of a Concical Triangular Connection in Implants: A New Proposal
(MDPI, 2022)
Conical implant–abutment connections are popular for their stability; however, in other conditions, such as excessive force, implants and abutments can absorb all the stress. Some connections with three points of support ...

A simple procedure to evaluate Cauchy stress tensor at the macro level based on computational micromechanics under general finite strain states
(Elsevier Science, 2018-02)
This paper presents a new methodology to evaluate the Cauchy stress tensor at the macro level in computational micromechanics models. The use of control nodes to specify boundary conditions of a Representative Volume Element ...
Generalized viscoelastic model for laminated beams using hierarchical finite elements
(Elsevier, 2020-03)
The formulation of an enriched hierarchical one-dimensional finite element suitable to analyze the rheological behavior of thick arbitrarily laminated beams is presented. The formulation is based on the Equivalent Single ...
A coupled FEM-SBFEM approach for soil-structure-interaction analysis using non-matching meshes at the near-field far-field interface
(Elsevier, 2019-06)
Nowadays numerical simulation of soil structure interaction (SSI)is applied to different problems, such as the construction of reliable earthquake-resistant structures. To analyze SSI considering unbounded domains, a ...
Creation of a three-dimensional model of the mandible and the TMJ in vivo by means of the finite element method.
(Quintessenz Verlags GmbH, 2002-04-01)
The aim of this study was to develop a three-dimensional finite element model of the mandible, including its TMJ. The model consisted of 7942 nodes and 41,010 elements, which were obtained from a convergence test, done ...
