Abstract:
A study is made of the relative accuracy provided by seven different types of finite elements in the approximate analysis of plate bending. The Kirchoff plate bending theory is assumed, and stiffness matrices for three rectangular and four triangular elements are considered. Included among these is a newly developed triangular element which provides for full displacement comparability along the edges of adjacent elements. Analyses are made with each of these elements of the central deflection in eight different rectangular plate systems, using five different mesh sizes. Two of the rectangular elements and the compatible triangular element are found to give results which converge toward the correct answer as the mesh size is refined.
