Abstract: Nonaffine deformations of amorphous nanostructures have been studied within the framework of a random matrix model. Near the boundary between amorphous and crystalline solids, nonaffine deformations of amorphous solids lead to the formation of a boundary region with altered effective elastic properties. It is shown that the thickness of the boundary region has the same order of magnitude as the scale of non-affine deformations.

Keywords: nonaffine deformations, amorphous bodies, random matrices.
