In this study, we used MEF90 to investigate the impact of defects, such as pre-deflected cracks and chemical impurities, and interface regions, such as angled interfaces, on the properties of 2D materials. To create the initial geometry for the MEF90 simulations, we introduced a crack into the 2D material system at the interface region, with the crack tip positioned exactly in the middle of the interface. The crack length was set to be half of the entire geometry length, at 20 units, and the interface width was set to be a tenth of the geometry length, at 0.4 units. The crack was also pre-deflected by 2 units to simulate the effect of pre-existing defects on the material's behavior. Specifically, we find that the material exhibits unit less behavior, meaning that it does not depend on the unit of measurement used to describe its properties. This characteristic allows us to apply the material to a wide range of scales in the continuum, as we are not limited by the unit of measurement used to describe it.
