[Pw_forum] young modulus

[Mansoureh Pashangpour]

Dear all,
After scf runs for different strains along zigzag and armchair directions I
found stress tensor for monolayer and bilayer graphene. I know slop of
stress-strain curve is young modulus. element11 of stress in terms of
strain along a1 direction gives one of Y modulus and element22 gives other
one. Is it needed any rescaling to find Y modulus for bilayer of graphene?
