Materials selection in micro- or nano-mechanical design: Towards new Ashby plots for small-sized materials

Abstract

Conventional Ashby plots for material selection may not appropriately describe material properties at small-length scales, new plots taking account of size effects are urgently needed for micro- or nano-mechanical design. Here, I show strength–modulus, strength–density, and size effect–Peierls stress plots for various solid materials at small scales.
