Harnessing mechanical instabilities at the nanoscale to achieve ultra-low stiffness metals

The rule of mixtures usually causes composite properties to fall between the maximum and minimum of the parent phases. Here, the authors use large-scale molecular dynamics simulations to break that rule by stabilizing a negative stiffness state in fully dense nickel-aluminum nanowires to achieve ult...
