A Study of the Effect of Element Shape on the Accuracy of Various 2D Finite Element Formulations

Abstract

<p>Linear Isoparametric elements and elements based on the Constant Strain Triangle are developed and incorporated into a computer program, for two dimensional stress analysis on mini computers. These elements are compared at element level using the Weighted Eigenvalue method and in assemblage using sensitivity analysis. Further, a method of predicting results based on the data generated during the comparisons at the element level is also presented. As an application of the computer program, analysis of a porcelain insulator is also included.</p>
