Near-surface lattice instability in 2D fiber and half-space

We study the vibrational stability of model 2D solids with surfaces when large strains are present. For a fiber under compression, the phonon analysis correctly predicts the behavior of the buckling instability. For half-space under tension and compression, we find that (a) instabilities of the surf...
