Uniaxial Testing of Graphene

Dear All !!

I was performing uni-axial tensile testing of graphene on laamps. nevertheless i am able to perform the simulation successfully but i’m not getting the accurate result. it is widely known that young’s modulus of graphene is 1Tpa . BUt through the simulation result i’m getting only around 0.165 Tpa . Can anybody look into my input file and logs file to tell me what is wrong . I shall be very thankful to all .
Thanks in Advance !!

How do you know that the potential you are using (whatever it is), will

give the correct Young’s modulus?
