A locking-free Reissner-Mindlin quadrilateral element
نویسندگان
چکیده
On arbitrary regular quadrilaterals, a new finite element method for the Reissner-Mindlin plate is proposed, where both transverse displacement and rotation are approximated by isoparametric bilinear elements, with local bubbles enriching rotation, and a local reduction operator is applied to the shear energy term. This new method gives optimal error bounds, uniform in the thickness of the plate, for both transverse displacement and rotation with respect to H1 and L2 norms.

On the Convergence of Weissman-taylor Element for Reissner-mindlin Plate
In this paper, we study the Weissman-Taylor rectangular element for the Reissner-Mindlin plate [12] model and provide a convergence analysis for the transverse displacement and the rotation. We show that the element is stable and locking free, thereby improve the results of [8] and [9].
متن کاملLocking Effects in the Finite Element Approximation of Plate Models
We analyze the robustness of various standard finite element schemes for a hierarchy of plate models and obtain asymptotic convergence estimates that are uniform in terms of the thickness d . We identify h version schemes that show locking, i.e., for which the asymptotic convergence rate deteriorates as ¿->0, and also show that the p version is free of locking. In order to isolate locking effec...
متن کاملA Family of Discontinuous Galerkin Finite Elements for the Reissner-Mindlin Plate
We develop a family of locking-free elements for the Reissner– Mindlin plate using Discontinuous Galerkin techniques, one for each odd degree, and prove optimal error estimates. A second family uses conforming elements for the rotations and nonconforming elements for the transverse displacement, generalizing the element of Arnold and Falk to higher degree.
متن کاملLocking - free Reissner – Mindlin elements without reduced integration q
In a recent paper of Arnold et al. [D.N. Arnold, F. Brezzi, L.D. Marini, A family of discontinuous Galerkin finite elements for the Reissner–Mindlin plate, J. Sci. Comput. 22 (2005) 25–45], the ideas of discontinuous Galerkin methods were used to obtain and analyze two new families of locking free finite element methods for the approximation of the Reissner–Mindlin plate problem. By following t...
متن کاملTwo lower order nonconforming rectangular elements for the Reissner-Mindlin plate
In this paper, we propose two lower order nonconforming rectangular elements for the Reissner-Mindlin plate. The first one uses the conforming bilinear element to approximate both components of the rotation, and the modified nonconforming rotated Q1 element to approximate the displacement, whereas the second one uses the modified nonconforming rotated Q1 element to approximate both the rotation...
