This paper has investigated the mechanical properties of an N-graphdiyne nanosheet (C18N6) using molecular dynamics simulation. To this aim, C18N6 nanosheets were modeled in a molecular dynamics environment, and the size effect was studied on these sheets. It was found that within the range of 20-50 nm and in thermal conditions higher than room temperature, the size effect was negligible. Accordingly, the strain rate and temperature effects were studied on sheets with smaller sizes. The results indicated that at the temperature of 500 K, the tensile strength decreased with the strain rate in both armchair and zigzag sheets. Moreover, the temperature was inversely related to the strength of the zigzag and armchair sheets. The findings of this work offer new opportunities in the design of the next generations of heat management nanodevices or nanoelectronics.
