Complex modal analysis of a vertical rotor through finite element method
(2012)
Natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical and complex modal analysis. The mathematical modeling was based ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Modeling reinforced concrete structures using coupling finite elements for discrete representation of reinforcements
(2018-09-15)
This paper presents an alternative methodology to represent rebars and their bond-slip behavior against concrete based on coupling finite elements. Among the main features and advantages of the proposed technique are: (i) ...
A coupling technique for non-matching finite element meshes
(Elsevier B.V., 2015-06-15)
This paper presents a novel technique for coupling non-matching finite element meshes, based on the use of special finite elements termed coupling finite elements (CFEs), which share nodes with non-matching meshes. The ...
Simplified qualitative discrete numerical model to determinate cracking pattern in brittle materials by means of finite element method
(Hindawi, 2017-07-02)
This paper presents the formulation, implementation, and validation of a simplified qualitative model to determine the crack path of solids considering static loads, infinitesimal strain, and plane stress condition. This ...
Convergence of adaptive finite element methods for eigenvalue problems
(World Scientific, 2009-05)
In this paper we prove convergence of adaptive finite element methods for second-order elliptic eigenvalue problems. We consider Lagrange finite elements of any degree and prove convergence for simple as well as multiple ...
Simulations of incompressible fluid flows by a least squares finite element method
(2005-07-01)
In this work simulations of incompressible fluid flows have been done by a Least Squares Finite Element Method (LSFEM) using velocity-pressure-vorticity and velocity-pressure-stress formulations, named u-p-ω) and u-p-τ ...

Finite element evaluation of three methods of stable fixation of condyle base fractures
(Churchill Livingstone, 2014-10-01)
The surgical treatment of mandibular condyle fractures currently offers several possibilities for stable internal fixation. In this study, a finite element model evaluation was performed of three different methods for ...
Numerical electroseismic modeling: A finite element approach
(Elsevier Science Inc, 2012-02)
Electroseismics is a procedure that uses the conversion of electromagnetic to seismic waves in a fluid-saturated porous rock due to the electrokinetic phenomenon. This work presents a collection of continuous and discrete ...
