Stability

      [Mechanical response of Au (001) nanoplate under uniaxial stress condition along [100] direction] Under mechanical loading, metal nanoplates fail via elastic instability rather than the yield strength. As a result, we observed a unique “smaller is weaker” trend. We provided numerical and theoretical evidence to show that the nanoplates exhibit an intermediate […]

Dislocations

Nanomechanics, Research

[Stress-drop due to phonon scattering around dislocation core while it is in motion] Unlike continuum, the motion of dislocation in nanoscale system induces unusual phenomenon. Through atomistic simulations, we observed that the internal effective stress of the system is always smaller than the externally applied stress during the dislocation motion. And we defined this unusual […]
