INTRODUCTION
- FE equations based on Reissner-Mindlin plate
theory will be developed. - FE equations of shells will be formulated by
superimposing matrices of plates and that of 2D
solids. - Computationally tedious due to more DOFs.

PLATE ELEMENTS
- Geometrically similar to 2D plane stress solids
except that it carries only transverse loads.
Leads to bending. - 2D equivalent of the beam element.
- Rectangular plate elements based on
Reissner-Mindlin plate theory will be developed
