The structural performance of double-walled C(5,5)@BN(10,10) and C(5,5)@C(10,10) nanotubes subject to high temperatures is investigated through molecular dynamics simulations. It is found that the inner tube C(5,5) in the C(5,5)@BN(10,10) exhibits less distortion than that in the C(5,5)@C(10,10) at annealing temperatures of 3500 and 4000 K. The C(5,5)@BN(10,10) and C(5,5)@C(10,10) models with different axial compressive strains are optimized using the universal force field (UFF) method. It is found that the critical buckling strains of the inne...
