Formulation of solid-shell finite elements with large displacements considering different transverse shear strains approximations
(Elsevier Science, 2017-08)
This work presents a general formulation and implementation in solid-shell elements of the refined zigzag theory and the trigonometric shear deformation theory in an unified way. The model thus conceived is aimed for use ...
Analysis of elastic functionally graded materials under large displacements via high-order tetrahedral elements
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
The purpose of this study is to present a position based tetrahedral finite element method of any order to accurately predict the mechanical behavior of solids constituted by functionally graded elastic materials and ...
A Fixed Grid method for hyperelastic models in large strain analysis using the level set method
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2014)
A Fixed Grid Finite Element Method (FGFEM) in addition to a Mooney-Rivlin hyperelastic model is introduced. This method uses the mixed finite element formulation to treat the elements, but classifying these in a fixed ...
Implementation of the refined zigzag theory in shell elements with large displacements and rotations
(Elsevier, 2014-08)
This work shows a possible implementation of the refined zigzag theory in elements based on Simo’s shell theory. Refined zigzag theory can deal with composite laminate economically, adding only two nodal degrees of freedom, ...
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. ...
Long-term foundation response to repetitive loading
(American Society of Civil Engineers, 2014)
Repetitive loading can induce volumetric and shear strain accumulation in soils and affect the long-term performance of engineered
and natural geosystems.Ahybrid numerical scheme based on theFEMis implemented to analyze ...
On the strong discontinuity approach in finite deformation settings
(John Wiley & Sons Ltd, 2003-05)
Taking the strong discontinuity approach as a framework for modelling displacement discontinuities and strain localization phenomena, this work extends previous results in innitesimal strain settings to finite deformation ...
Formulação de um elemento finito de viga tridimensional para dinâmica de corpos flexíveis
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2020-09-24)
In the last decades, many efforts have been done to build models to simulate multiphysics
analisys. For instance, in aeronautical projects, computational models coupling flight dynamics,
structural mechanics, aerodynamics ...
Finite element formulation for large displacement analysis
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2009)
Abstract: In structural engineering, shells are usually curved objects which can support remarkable external forces without fracture or damage. Due to this remarkable stiffness behaviour and the low amount of material used ...
