An Optimally Controlled Four-Node Quadrilateral Element for Reissner-Mindlin Plate
A four-node quadrilateral plate bending element of Reissner-Mindlin plate, which uses bilinear interpolations for both rotations and transverse deflection, has been developed by employing a technique similar to the quasi-conforming method. Success is achieved to control the hourglass modes produced by the employment of one-point quadrature in the implementation of the element U1. Numerical results for a variety of plate problems are presented to show the accuracy, the convergency and the efficiency of the present element.
