Hello everyone,
I am using the lammps to simulate the zinc oxide and graphene by following a paper (Molecular dynamics prediction of interfacial strength and validation through atomic force microscopy). I want to obtain the relationship of force and displacement (distance between zinc oxide and graphene) shown in fig.1 of the paper. However, the figure I got was so different with the one shown in that paper. I am not sure where the mistakes are. Also, Can you tell me the difference between force and stress of atom and how to calculate them? I attached my input file (move2), log file (output), and the figure I got. Please help me. Let me know if you have any question. Thank you so much!
