10.2 FINITE ELEMENT ANALYSIS OF PLATES
10.2.1 Introduction
A plate is a three-dimensional structure bounded by two parallel planes separated by a distance, h, denoting thickness of the plate. The x–y plane at z = 0, which is equidistant from two bounding planes, is called the middle surface of the plate. In the linear elastic plate theory for isotropic material, the problem uncouples into in-plane and out-of-plane problems, depending on whether the loading is parallel to the x–y plane or normal to it. Finite element formulation for the parallel loading has already been presented in Chapter 7 for plane stress or plane strain situation. In this section, only the bending of plates is presented when the loading is normal to the x–y plane. An interested ...
