A Hu–Washizu variational approach to self-stabilized virtual elements: 2D linear elastostatics

چکیده
Abstract An original, variational formulation of the Virtual Element Method (VEM) is proposed, based on a Hu–Washizu mixed statement for 2D linear elastostatics. The proposed framework appears to be ideal VEs, whereby compatibility enforced in weak sense and strain model can prescribed priori, independently unknown displacement model. It shown how ensuing freedom definition conveniently exploited self-stabilized possibly locking-free low order VEs. superior performances VEs formulated within this has been verified by application several numerical tests.

متن کاملA MATLAB Code for Three Dimensional Linear Elastostatics using Constant Boundary Elements
Present work presents a code written in the very simple programming language MATLAB, for three dimensional linear elastostatics, using constant boundary elements. The code, in full or in part, is not a translation or a copy of any of the existing codes. Present paper explains how the code is written, and lists all the formulae used. Code is verified by using the code to solve a simple problem w...
متن کاملA Variational Approach to Image Discusion in Non-Linear Domains
Image filtering methods are designed to enhance noisy images captured in situations that are problematic for the camera sensor. Such noisy images originate from unfavourable illumination conditions, camera motion, or the desire to use only a low dose of ionising radiation in medical imaging. Therefore, in this thesis work I have investigated the theory of partial differential equations (PDE) to...
متن کاملA linear algebraic approach to representing and computing finite elements
We use standard ideas from numerical linear algebra plus orthogonal bases for polynomials to compute abstract finite elements. We express nodal bases in terms of orthogonal ones. This paradigm allows us to differentiate polynomials, evaluate local bilinear forms, and compute with affine equivalent elements. It applies not only to Lagrangian elements, but also to Hermite elements, H(div) and H(c...
متن کاملA numerical technique for solving a class of 2D variational problems using Legendre spectral method
An effective numerical method based on Legendre polynomials is proposed for the solution of a class of variational problems with suitable boundary conditions. The Ritz spectral method is used for finding the approximate solution of the problem. By utilizing the Ritz method, the given nonlinear variational problem reduces to the problem of solving a system of algebraic equations. The advantage o...
