Deriving Shape Functions for Hexahedral Element by Natural Coordinate System and Verified

P. Reddaiah

Abstract

In this paper, I derived shape functions for hexahedral element by using natural Co-ordinate system and also I verified two verification conditions for shape functions. First verification condition is sum of all the shape functions is equal to one and second verification condition is each shape function has a value of one at its own node and zero at the other nodes. For computational purpose I used Mathematica 9 Software [2].

Keywords

Hexahedral element, Natural Co-ordinate system, Shape functions.
