Stability Analysis of Wilson's Element for Incompressible Elasticity
نویسنده
چکیده
In this work, the rectangular nonconforming Wilson element in solving incompress-ible elastic equation is analyzed. Although the element does not satisses the inf-sup condition (in a mixed formulation), it still can be used to compute the displacement successfully. If a simple post-processing is applied, the pressure converges, too. An optimal convergence rate is established for both displacement and smoothed pressure.

Application of Barycenter Refined Meshes in Linear Elasticity and Incompressible Fluid Dynamics
The paper demonstrates that enhanced stability properties of some finite element methods on barycenter refined meshes enables efficient numerical treatment of problems involving incompressible or nearly incompressible media. One example is the linear elasticity problem in a pure displacement formulation, where a lower order finite element method is studied which is optimal order accurate and ro...
متن کاملOn the stability of BDMS and PEERS elements
Using “Fortin operators” we give a new proof of stability for Stenberg’s family of BDMS elements in linear elasticity. Our approach yields the inf-sup condition with respect to the standard norms, which is indispensable for a posteriori error analysis. Furthermore our technique allows the construction of another family of finite elements strongly related to the classical PEERS element. The give...
متن کاملNearly Incompressible Linear Elasticity Using Simplicial Meshes
We present two finite element methods for simplicial meshes to approximate the solution of the problem of nearly incompressible elasticity. Although both approaches are based on mixed formulations of linear elastic equations and biorthogonal systems, one of them is nonsymmetric, and the other symmetric. An interesting feature of both approaches is that displacement-based formulations can be obt...
متن کاملInf-sup stable finite element pairs based on dual meshes and bases for nearly incompressible elasticity
We consider finite element methods based on simplices to solve the problem of nearly incompressible elasticity. Two different approaches based respectively on dual meshes and dual bases are presented, where in both approaches pressure is discontinuous and can be statically condensed out from the system. These novel approaches lead to displacement-based low order finite element methods for nearl...
متن کاملExact energy and momentum conserving algorithms for general models in nonlinear elasticity
Implicit time integration schemes that inherit the conservation laws of total energy, linear and angular momentum are considered for initial boundary-value problems in ®nite-deformation elastodynamics. Conserving schemes are constructed for general hyperelastic material models, both compressible and incompressible, and are formulated in a way that is independent of spatial discretization. Three...
