On the uniform approximation of the Reissner-Mindlin plate model by p/hp finite element methods
نویسندگان
چکیده
We study the approximation of the Reissner-Mindlin plate using the p/hp version of the finite element method (FEM). Our goal is to identify a method that: (i) is free of shear locking, (ii) approximates the boundary layer independently of the thickness of the plate and (iii) converges exponentially with respect to the number of degrees of freedom. We will consider both standard and reduced constraint/mixed formulations, in the context of the p/hp version of the FEM, and we will give guidelines for the construction of appropriate mesh-degree combinations that accomplish the above three goals, using straight as well as curved sided elements.

A Superconvergent Finite Element Scheme for the Reissner-mindlin Plate by Projection Methods
The Reissner-Mindlin model is frequently used by engineers for plates and shells of small to moderate thickness. This model is well known for its “locking” phenomenon so that many numerical approximations behave poorly when the thickness parameter tends to zero. Following the formulation derived by Brezzi and Fortin, we construct a new finite element scheme for the Reissner-Mindlin model using ...
متن کاملMESH GENERATION FOR hp TYPE FINITE ELEMENT ANALYSIS OF REISSNER-MINDLIN PLATES
Efficient finite element (FE) analyses of Reissner-Mindlin (RM) plate bending problems require a combination of high-order polynomial trial functions (p-extension) and locally refined meshes, or, in short, an hp-extension of the FE method. In the optimal case, exponential rates in the convergence of the error in energy norm can be obtained by such a discretization. This contribution discusses s...
متن کاملFinite Element Computations for the Reissner-mindlin Plate Model
We consider the nite element (FE) approximation of the Reissner-Mindlin (RM) plate model, and indicate how to design meshes that yield accurate results when the p=hp version of the standard FE method is used. These guidelines allow quantities of engineering interest to be numerically predicted with great conndence near the boundary. We illustrate this through numerical computations in the case ...
متن کاملOn Mixed Finite Element Methods for the Reissner-mindlin Plate Model
In this paper we analyze the convergence of mixed finite element approximations to the solution of the Reissner-Mindlin plate problem. We show that several known elements fall into our analysis, thus providing a unified approach. We also introduce a low-order triangular element which is optimalorder convergent uniformly in the plate thickness.
متن کاملAn Overlapping Domain Decomposition Method for the Reissner-mindlin Plate with the Falk-tu Elements
Abstract. The Reissner-Mindlin plate theory models a thin plate with thickness t. The condition numbers of finite element approximations of this model deteriorate badly as the thickness t of the plate converges to 0. In this paper, we develop an overlapping domain decomposition method for the Reissner-Mindlin plate model discretized by the Falk-Tu elements with the convergence rate which does n...
