Using this initial geometry as the starting point, we ran a series of MEF90 simulations to study the influence of the crack and interface on the electronic, optical, and mechanical behavior of the 2D materials. We varied the interface toughness over a range of values, from 0.010 to 0.100, incrementing at 0.01 each time, for a total of 10 trials. The amount of defects was also varied, ranging from 0, 5, 10, and 15 defects. The angles of the interface were varied as well, ranging from 0 to 50 degrees in increments of 2.5 degrees. For each angle, we used all of the defect amounts, and for each defect amount, we ran 10 simulations for each of the interface toughness values. This resulted in a total of 520 base simulations, which allowed us to thoroughly investigate the influence of defects and interface regions on the properties of 2D materials. In order to gain even more accurate results, we simulated incremental values within the increments themselves, the most common ones ranging from 0.031-0.049 interface toughness. This allowed for a trend to be identified amongst the different angled values, as the results share little commonality.
