The effect of the aspect ratio on Young's modulus (E) of boron nitride nanosheets (BNNS) was evaluated using molecular dynamics simulation techniques employing the Tersoff potential field. The aspect ratio (L/B) of BNNS may influence the elastic properties; therefore, the values are varied from 2 to 12. Our results revealed that the E of BNNS decreased with an increase in the aspect ratio up to 9 and then became stable in both the armchair and zigzag directions. It is anticipated that the result will provide a beneficial understanding of the elastic properties of BNNS, which can aid in the design and implementation of structured and tailored NEMS devices, transistors, sensors, lightweight materials, and automotive sectors.
