Abstract

This is the second part of a two‐part paper on plate bending elements with shear effects included. This paper presents a new four‐node, 12‐d.o.f. quadrilateral plate bending element valid for the analysis of thick to thin plates. The element called DKMQ, has a proper rank (contains no spurious zero‐energy modes), passes the patch test for thin and thick plates in an arbitrary mesh and is free of shear locking. Very good results have been obtained for thin and thick plates by the element. An extended DKT element for thick‐plate bending analysis is evaluated in Part I.19
