Abstract
Several methods have been employed to calculate the mechanical properties of GaN with reliable results. In this work, we employed the energy strain method from first-principles calculation to review the structural and mechanical properties of GaN. From our results, we observed that there is agreement in some of the elastic constants when compared with literature review.
