摘要：
This paper has introduced two kinds of combined hybrid variational formulations for plate bending finite elements based upon the Reissner-Mindlin theory, according to whether assumed constant moment stress is introduced when assumed constant shear stress has been introduced. Due to two options for incompatible displacement modes, four new types of combined hybrid elements are proposed. A set of standard tests for both thin and thick plates show that new elements perform well. (c) 2006 Elsevier Inc. All rights reserved.
