Developments of Mindlin‐Reissner Plate Elements
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 Since 1960s, how to develop high‐performance plate bending finite elements based on different plate theories has attracted a great deal of attention from finite element researchers, and numerous models have been successfully constructed. Among these elements, the most popular models are usually formulated by two theoretical bases: the Kirchhoff plate ...

Application of Galerkin Method to Kirchhoff Plates Stochastic Bending Problem
International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 In this paper, the Galerkin method is used to obtain approximate solutions for Kirchhoff plates stochastic bending problem with uncertainty over plates flexural rigidity coefficient. The uncertainty in the rigidity coefficient is represented by means of parameterized stochastic processes. A theorem of Lax‐Milgram type, about existence and uniqueness of

Shock and Vibration, Volume 2014, Issue 1, 2014., 2014 This paper presents formulations for a Timoshenko beam subjected to an accelerating mass using spectral element method in time domain (TSEM). Vertical displacement and bending rotation of the beam were interpolated by Lagrange polynomials supported on the Gauss‐Lobatto‐Legendre (GLL) points.

A High Order Theory for Linear Thermoelastic Shells: Comparison with Classical Theories
Journal of Engineering, Volume 2013, Issue 1, 2013., 2013 A high order theory for linear thermoelasticity and heat conductivity of shells has been developed. The proposed theory is based on expansion of the 3‐D equations of theory of thermoelasticity and heat conductivity into Fourier series in terms of Legendre polynomials.

Stabilized Plane and Axisymmetric Lobatto Finite Element Models [PDF]
, 2015 High order elements are renowned for their high accuracy and convergence. Among them, Lobatto spectral finite elements are commonly used in explicit dynamic analyses as their mass matrices when evaluated by the Lobatto integration rule are diagonal ...

Mathematical Problems in Engineering, Volume 2012, Issue 1, 2012., 2012 Deformation of partially composite beams under distributed loading and free vibrations of partially composite beams under various boundary conditions are examined in this paper. The weak‐form quadrature element method, which is characterized by direct evaluation of the integrals involved in the variational description of a problem, is used.

A Comparative Study Between the Finite Element Analysis and the Isogeometric Analysis Within a Parametric Environment. [PDF]
, 2022 Vanlig praksis for en design prosess i dag, er at arkitekter og ingeniører jobber i ulik programvare. Det er derimot fordelaktig med et tett samarbeid, for å kunne skape visuelt pene og strukturelt smarte design.

On the stability of mixed polygonal finite element formulations in nonlinear analysis
International Journal for Numerical Methods in Engineering, Volume 125, Issue 9, 15 May 2024.Abstract This article discusses the accuracy and stability of the pressure field in nonlinear mixed displacement‐pressure finite element formulations in solid mechanics. We focus on two‐dimensional mixed polygonal finite element formulations with linear displacement and constant pressure approximations in particular.

International Journal of Rotating Machinery, Volume 2008, Issue 1, 2008., 2008 This paper is concerned with the dynamic behavior of the rotating composite shaft on rigid bearings. A p‐version, hierarchical finite element is employed to define the model. A theoretical study allows the establishment of the kinetic energy and the strain energy of the shaft, necessary to the result of the equations of motion.
