This presentation is part of : Surface Stress in Nature and Technology

Some fundamental aspects of surface modelling

Ian Murdoch, University of Strathclyde, University of Strathclyde, Livingstone Tower, 26 Richmond Street, Glasgow, G1 1XH, United Kingdom

Attention will be drawn to three aspects of surface modelling : (i) delineation of the (scale-dependent) geometrical boundary of a body via molecular considerations, (ii) identification of the highly inhomogeneous interfacial region between a body and its exterior, and its modelling as a bidimensional continuum involving interfacial excess quantities, and (iii) presentation of an example involving thermal expansion which highlights the importance of surface effects for small-scale bodies.
