Abstract

A model of geometrical interface with inherent elastic stress is developed. The general formulas for interface stress, tension and free energy density of condensed matter as well as their relations are derived. The constitutive relationship of the interface is also discussed. The results so obtained all agree with the current theories, and some new conclusions are drawn.
