Molecular Dynamics Study of Superelastic Performance of a β-Si3N4Nanohelical Coil.
Superealsticity behavior has been discovered for the β-Si3N4nanohelical coil. By a series of cyclic loading and unloading simulation tests, the nanohelical coil could elastically recover its original shape after a relatively long axial tension far beyond the elastic limit, accompanying little residual plastic deformation. The spring constant is first a steady-state value of 0.72 N m-1in the linear stage and then increases dramatically for up to 1.5 N m-1in the nonlinear region. The fascinating performance of the nanocoil makes it stand out from its bulk counterparts in the development of future electronic devices such as nanoscale elastic energy storage.
