| Abstract: | The physical mechanism responsible for nonlinear elastic, hysteretic, and discrete memory response
of nonlinear mesoscopic elastic solids has to date not been identified.We show, by nanoindenting mica
single crystals, that this response is most likely due to the formation of dissipative and fully reversible,
dislocation-based kink bands. We further claim that solids with high c=a ratios, which per force are
plastically anisotropic, should deform by kinking, provided they do not twin. These kinking nonlinear
elastic solids include layered ternary carbides, nitrides, oxides, and semiconductors, graphite, and the
layered phases, such as mica, present in nonlinear mesoscopic elastic solids. |
