Comparative Stability Analysis of Boron Nitride Nanotube using MD Simulation and Nonlocal Elasticity Theory

Boron Nitride Nanotube (BNNT) is a promising nano sized structure with superior electrical, physical, and mechanical properties comparing to Carbon nanotube. Higher Young’s modulus, oxidation resistance, hardness, corrosion resistance, durability in high temperature, piezoelectric and pyroelectric characteristics are some featured characteristics of BNNT. In this paper the critical buckling load of Boron Nitride Nanotube is investigated. Two different method is used. First Eringen’s nonlocal elasticity theory is employed to obtain size-dependent critical buckling loads. Then, LAMMPS software is used to simulate molecular dynamics and obtain critical buckling loads. Zigzag (5,5) BNNT with 400 atoms is examined into MD simulation analyzes.
