Finite Element Analysis

One of the best resources for FEA pdfs is the Colorado University structural analysis course.  The coursework had been built up over a number of years, starting in 1987.  The website itself was relatively ancient having been launched way back in 1998.  Now sadly it seems to have been removed from the Public Domain.  The data here is a copy of that website from a moment in time, wherein the original content is the construction of Carlos Felippa.

The notes have a focus on how to actually write FEA software.  Hence there are in-depth sections to do with assembly of simple single element models and more complex multi element models.  Quite a few worked, numerical examples are provided along with code snippets written for Matlab.

A fantastic resource for students and engineers.
