Programing the Finite Element Method with Matlab

Programing the Finite Element Method withMatlabJack Chessa 3rd October 20021 IntroductionThe goal of this document is to give a very brief overview and directionin the writing of Finite Element code using Matlab . It is assumed that thereader has a basic familiarity with the theory of the Finite Element Method ,and our attention will be mostly on the implementation. An example finiteelement code for analyzing static linear elastic problems written in Matlabis presented to illustrate how to program the Finite Element Method . Theexample program and supporting files are available NotationFor clarity we adopt the following notation in this paper; the bold italics fontvdenotes a vector quantity of dimension equal to the spacial dimension of displacement or velocity at a point, the bold non-italicizedfontddenotes a vector or matrix which is of dimension of the number ofunknowns in the discrete system matrix like the stiffness matrix,an uppercase subscript denotes a node number whereas a lowercase subscriptin general denotes a vector component along a Cartesian unit vector.
