Now I am studying Continuum Mechanics by means of Mathematica. I really want to use TContinuumMechanics and Tensorial developed by Jean-François Gouyet et al.But,as you know, I really have no enough money to cover these as a student.

Could you deliver a version on them for free? I just use them to study the corresponding courses, and never use for Commercial Purposes! Thanks a lot !

who  can tell me more about the critical thickness theory ?I will be very excited if you   can introduce some reference to me.I know that critical thickness theory is solved rigorously and ursed to validated a useful approximation which is combined with slip distance theory modified for a finite structure size . (physical life review letters :elastic limit and strain hardening of thin wires in torsion)
