TODO - In this study, a nonlinear, spring-based finite element approach is employed in order to predict the nonlinear mechanical response of graphyne structures under  shear loading. Based on Morse potential functions, suitable nonlinear spring finite  elements are formulated simulating the interatomic interactions of different  graphyne types. Specifically, the four well-known types of γ-graphyne, i.e.,  graphyne-1 also known as graphyne, graphyne-2 also known as graphdiyne, graphyne-3,  and graphyne-4 rectangular sheets are numerically investigated applying appropriate  boundary conditions representing shear load. The obtained finite element analysis  results are employed to calculate the in-plane shear stress-strain behaviour, as  well as the corresponding mechanical properties as shear modulus and shear strength.  Comparisons of the present graphyne shearing response predictions with other  corresponding estimations are performed to validate the present research results.
