I used to support Autocad 2000 and Pro-Engineer at a previous job; but
they're high-dollar. I'm not aware of any free packages that fully
featured. You might try Wikipedia. They usually have lists or
comparison matrixes of types of software. You probably need a package
that does 3D modeling to do what you're asking.
The stress testing is called "Finite element analysis", to give ya'
something to google on. Or check:
Some software offers inexpensive student versions. Eg, AutoCAD for $160
at the community college bookstore, if you're registered for the $60 CAD
