Evaluation of Artificial Ageing Methods for Glass

Surface damage that accumulates on the surface of glass is known to govern the strength of this material. It would therefore be very useful to use artificial ageing techniques to replicate this level of damage; this would allow a rapid and cost effective assessment of the expected glass strength and...
