DESCRIPTION:Ductile metals fail by the nucleation\, growth\, and coalescen
 ce of voids. We have identified the principal mechanisms by which nanosize
 d voids grow: shear loops\, prismatic loops and twinning. Although prismat
 ic loops and twinning are well known deformation mechanisms\, the emission
  and expansion of shear loops has a special requirement that the extremiti
 es remain attached to the void surface. Using molecular dynamics simulatio
 ns\, we can observe the expansion of the voids and the associated elementa
 ry deformation mechanisms.
