Abstract: A mathematical framework is developed to study the mechanical behavior of material surfaces. The tensorial nature of surface stress is established using the force and moment balance laws. Bodies whose boundaries are material surfaces are discussed and the relation between surface and body stress examined. Elastic surfaces are defined and a linear theory with non-vanishing residual stress derived. The free-surface problem is posed within the linear theory and uniqueness of solution demonstrated. Predictions of the linear theory are noted and compared with the corresponding classical results. A note on frame-indifference and symmetry for material surfaces is appended.

Scaling Laws for Properties of Materials with Imperfect Interfaces
Huiling Duan,Bhushan Lal Karihaloo,J. Wang +2 more
- 01 Jan 2009
TL;DR: In contrast to the perfectly-bonded interfaces, the effective properties of heterogeneous materials containing inhomogeneities with imperfect interfaces become dependent upon the size of the inhomogenities as discussed by the authors.

TL;DR: In this article, a more realistic simulation about the elastic medium is presented by utilizing a three-parameter medium containing Winkler, Pasternak and damping coefficients, where both of the decreasing and increasing impacts of small scale influences are covered in the framework of a nonlocal strain gradient theory.

Surface energy effects on the yield strength of nanoporous materials containing nanoscale cylindrical voids
TL;DR: In this article, the effect of surface stress is taken into account to obtain a macroscopic yield function for nanoporous materials containing cylindrical nanovoids, where the Gurtin-Murdoch model of surface elasticity is incorporated in the generalized self-consistent method to obtain the closed-form expression for the transverse shear modulus of transversely isotropic nanoporous material.

The Linear Theory of Elasticity
Morton E. Gurtin
- 01 Jan 1973
TL;DR: Linear elasticity is one of the more successful theories of mathematical physics and its pragmatic success in describing the small deformations of many materials is uncontested The origins of the three-dimensional theory go back to the beginning of the 19th century and the derivation of the basic equations by Cauchy, Navier, and Poisson The theoretical development of the subject continued at a brisk pace until the early 20th century with the work of Beltrami, Betti, Boussinesq, Kelvin, Kirchhoff, Lame, Saint-Venant, Somigl

The Surface Tension of Solids
R Shuttleworth
- 01 May 1950
TL;DR: In this paper, a distinction is made between the surface Helmholtz free energy F, and the surface tension γ, which is the tangential stress (force per unit length) in the surface layer; this stress must be balanced either by external forces or by volume stresses in the body.
