Silica whiskers and fibres, with diameters ranging from a few A to 20nm have been modelled using classical molecular dynamics simulations. The surface structure of square cross-sectioned fibres has been characterised in terms of structural defect species and their population as a function of depth from the surface. The behaviour of a fibre under tensile strain is described, and the atomic scale structural origin of fracture is discussed.
