[Wien] elastic constants of hexagon

[Mehmet Topsakal]

Hi,

If your system is like graphene or graphane, elastic constants ( C11 and 
C12 ) can also be calculated in rectangular unit cell as in 
http://arxiv.org/abs/0908.2887 . That paper also explains a method to 
calculate in-plane stiffness and Poissons's Ratio.

If you are interested, ? can give you further scripts for those 
calculations.
