Does elastic stress modify the equilibrium corner angle?

We consider the influence of elasticity and anisotropic surface energy on the energy-minimizing shape of a two-dimensional void under biaxial loading. In particular, we consider void shapes with corners for which the strain energy density is singular

Numerical solution for the stress near a hole with corners in an infinite plate under biaxial loading

Autor: Wang, Weiqi, Spencer, Brian J.

We consider the elastic stress near a hole with corners in an infinite plate under biaxial stress. The elasticity problem is formulated using complex Goursat functions, resulting in a set of singular integro-differential equations on the boundary. Th

A Fokker-Planck reaction model for the epitaxial growth and shape transition of quantum dots

Autor: Wei, Chaozhen, Spencer, Brian J.

We construct a Fokker-Planck reaction model to investigate the dynamics of the coupled epitaxial growth and shape transition process of an array of quantum dots. The Fokker-Planck reaction model is based on a coupled system of Fokker-Planck equations
