Dear experts, I want to calculate the in-plane elastic constants c11 and c12 of an hexagonal 2D material. The cell parameter is of the form :
a(1 0 0) b(-0.5 (sqrt3)/2 0) Kindly assist how to apply the strain in order to determine c11 and also for c12. I intend to use energy-strain approach. Thanks and best regards A. A. Musari Department of Science Laboratory Technology Moshood Abiola Polytechnic, Abeokuta Nigeria
