Abstract

In this paper, we extend two rectangular elements for Reissner-Mindlin plate [9] to the quadrilateral case. Optimal H and L error bounds independent of the plate hickness are derived under a mild assumption on the mesh partition.

Key words: Reissner-Mindlin Plate; Quadrilateral Rotated Q1 element; Locking-free.
