چکیده

We present a systematic description and comparison of the Finite Element Method (FEM) with relatively new Virtual (VEM) for solving boundary value problems in linear elasticity, including primal mixed formulations. The highlights common base essential difference between FEM VEM: discretisation same (Galerkin) weak formulations assembly element-wise quantities, but different approaches to element shape functions. mathematical are complemented detailed computer implementation all methods, versions VEM, which will benefit readers willing develop their own computational framework. Numerical solutions several also presented order discuss weaker stronger sides methods.

Finite Element Methods for Linear Elasticity

Conditions for Stable Approximation Schemes Basic idea: Mimic structure of continuous problem. To establish stability of continuous problem, only used last two spaces in top sequence and last three spaces in bottom sequence. Λn−1(K) dn−1 −−−→ Λn(K)→ 0 ↗ Sn−2 ↗ Sn−1 Λn−2(V) dn−2 −−−→ Λn−1(V) dn−1 −−−→ Λn(V)→ 0. Thus, look for five finite dimensional spaces connected by a similar structure, i.e.,...

Nonconforming Finite Element Methods for the Equations of Linear Elasticity

In the adaptation of nonconforming finite element methods to the equations of elasticity with traction boundary conditions, the main difficulty in the analysis is to prove that an appropriate discrete version of Korn's second inequality is valid. Such a result is shown to hold for nonconforming piecewise quadratic and cubic finite elements and to be false for nonconforming piecewise linears. Op...

Finite Element Methods for Convection Diffusion Equation

This paper deals with the finite element solution of the convection diffusion equation in one and two dimensions. Two main techniques are adopted and compared. The first one includes Petrov-Galerkin based on Lagrangian tensor product elements in conjunction with streamlined upwinding. The second approach represents Bubnov/Petrov-Galerkin schemes based on a new group of exponential elements. It ...

Stabilized Schemes for Mixed Finite Element Methods with Applications to Elasticity and Compressible Flow Problems

Stabilized iterative schemes for mixed nite element methods are proposed and analyzed in two abstract formulations. The rst one has applications to elliptic equations and incompressible uid ow problems, while the second has applications to linear elasticity and compressible Stokes problems. Convergence theorems are demonstrated in abstract formulations; applications to individual physical probl...
