Sorry, I got two links mixed up. This link

http://homepage.usask.ca/~ijm451/fin...resources.html

has references that are free or donation asked. The MYSTRAN software
is $200 for a 1 year license. Cheap in the software world.

A Finite Element Analysis package is worse than useless without mastery
of the basics. If you can't do it by hand, what you get from FEA could
get you or someone else killed. EAA still sells "Stress Without Tears"
that takes you through the basic principles and simplified equations for
doing stress analysis of aircraft structures. If you can't master that,
you aren't going to do much better learning the ins and outs of meshing
for FEA.
