Hi all,
This is my first post here so be gentle
If you are in need of a micromechanics/macromechanics and related calculations software you can use http://www.cadec-online.com/, a web based application that deals with those tedious calculations.
If you dont like the interface, or you want to do parametric studies, you can use the web service in Matlab, Mathematica or whatever: http://www.cadec-online.com/API.asmx
If you are in doubt use the help or ask here.
