Spectral/HP finite elements applied to linear and non-linear structural elastic problems
(Latin Amer J Solids StructuresSao PauloBrasil, 2007)
Linear smoothed polygonal and polyhedral finite elements
(Wiley, 2017)
The strain smoothing technique over higher order elements and arbitrary polytopes yields less accurate solutions than other techniques such as the conventional polygonal finite element method. In this work, we propose a ...
A two-dimensional linear assumed strain triangular element for finite deformation analysis
(American Society of Mechanical Engineers, 2006-11-19)
An assumed strain approach for a linear triangular element able to handle finite deformation problems is presented in this paper. The element is based on a total Lagrangian formulation and its geometry is defined by three ...
Adaptive non-nested multigrid methods

A solid-like FEM for geometrically non-linear 3D frames
(ELSEVIER SCIENCE SA, 2009)
This study presents a solid-like finite element formulation to solve geometric non-linear three-dimensional inhomogeneous frames. To achieve the desired representation, unconstrained vectors are used instead of the classic ...
Finite element computational modeling of externally bonded CFRP composites flexural behavior in RC beams
(TECHNO-PRESS, 2009)
This paper focuses on the flexural behavior of RC beams externally strengthened with Carbon Fiber Reinforced Polymers (CFRP) fabric. A non-linear finite element (FE) analysis strategy is proposed to support the beam flexural ...
Estudo de análises linear e não linear aplicado a flambagem
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2017-11-16)
Buckling can be considered a failure due to structural instability. Both design and engineering applications where slender elements are involved, buckling failure must be verified. In this context this research presents a ...
A positional FEM Formulation for geometrical non-linear analysis of shells
(LATIN AMER J SOLIDS STRUCTURES, 2008)
This work presents a fully non-linear finite element formulation for shell analysis comprising linear strain variation along the thickness of the shell and geometrically exact description for curved triangular elements. ...
