Effect of Surface Elasticity on Mode-3 Crack Stress Fields
arXiv:cond-mat/0412363
Abstract
The surface stress can have important effects on the elastic properties of nano-sized structures. Here we analyze the effect of surface stress on Mode-3 crack displacement and stress-field solutions under the assumption of linear elasticity. We show that surface effects generate non- terms near the crack-tip. We also find the effect of such terms on the conventional small-scale yielding assumption.
