7 results about "Surface elasticity" patented technology

Surface elasticity is due to the formation of a surface layer that has a different elastic property from that of a bulk [3–5,20]. Surface relaxation [20] and sometimes surface reconstruction [14] are the two profound mechanisms responsible for the formation of a surface layer.
