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.


Charles.


Don't see it on the EAA site but it is available on Amazon. * Just what
I'm looking for.

Thanks for the input all!

If you are inclined to take a look at the real thing, not the Reader's
Digest version, you can download almost anything you want for free
from this site at NASA.

http://euler9.tripod.com/analysis/asm.html

There are also links to much more.

That is fascinating Bud and I have actually reviewed it before. Somehow
though I have missed the section on the stress analysis of a steel tube
fuselage.

The books recommended by myself and others are primers. As such they
give the reader the needed context of where to apply a euler equation to
an airframe and how to apply it.

By the way, that is not in fact a NASA site, but a private site. The
NASA material can also be found on the NASA site though the last time I
looked. It is disheartening, but a lot of the NASA material (actually
NACA) has been made inaccessible in the last couple of years.

Now that the beers have worn off.....

does anybody know of a relatively inexpensive and
painless way to get a stress analysis done


No!
