Shear locking (SL) is a well studied phenomenon in the conventional displacement approach of Finite Element Methods (FEM). The problem is caused by the.

Abstract. A numerical scheme for the approximation of a parameter-dependent problem is said to exhibit locking if the accuracy of the approximations deteriorates as the parameter.

Locking arises when the only finite element solution that satisfies the zero shear strain condition corresponds to zero nodal displacements everywhere. This overstiffening can.

Gdansk University of Technology, Gdańsk, Poland ABSTRACT: In the present paper a short survey of the locking effect literature is given. As this area of scien- tific research is still.

We discuss the locking phenomenon of the finite element method for three-dimensional elasticity as Lamé constant λ→∞. Three kinds of finite elements are.

The finite-element method offers the most effective approach to computational (digital) simulation of problems in engineering mechanics. However, very large errors are often.

Introduction For the linear isotropic elasticity, it is well known that many numerical methods su er deteriorations in performance as the Lame constant ! 1, i.e., as the.

If the mesh size in the finite-element method is not taken to be fine enough, the numerical solution may exhibit locking; we explore the cause of this phenomenon and a.

The unknowns for the fluid and the solid are approximated by finite element subspaces of Lagrange and Arnold-Falk-Winther of order 1, which lead to a Galerkin scheme for the.

This phenomenon is called the shear, membrane, or shear–membrane locking and is typical for the displacement finite element method. Theoretical and.

In order to avoid the critical transverse shear locking phenomenon arising in the R–M plate theory, a simple and efficient locking-free polygonal R–M plate element.

There are ways in which shear locking can be prevented: – Increasing the number of elements across the wall thickness. – Using hexagonal elements (or.

It is well-known that the performance of certain commonly used finite elements deteriorates as v →0, a phenomenon called locking. We analyze this phenomenon and.
