Abstract
We present a brief overview and comparison of two different approaches to capturing surface effects on nanoscale materials. The first is a recently proposed computational model, the surface Cauchy-Born (SCB) model, which is a nonlinear, finite deformation continuum theory based upon Cauchy-Born kinematics. The second is classical linear surface elasticity based upon the framework proposed by Gurtin and Murdoch. Key distinctions that are discussed include the importance of linear versus nonlinear kinematics, and the dimensionality of the surface stress tensor.
