Questions of Interest

The questions of interest for the present workshop are :

  • What mechanisms and reactions are involved in the field of “stress corrosion” and what are their volume and time scale of action ? The phenomena of interest are : corrosion, dissolution, wetting, ion diffusion, water diffusion and speciation, structural relaxation, aging.
  • What are the kind of surface flaws inducing damage and their nucleation mechanisms ? What are their relations with glass strength ? How to produce pertinent controlled flaws ?
  • What are the relevant variables and their effect on these phenomena ? The variables of interest are : stress, composition, environment (gases, humidity, chemical attack), fictive temperature, bulk OH content, surface (treatments), time of aging, solarisation by laser impact, etc.
  • How to characterise these variables and surface properties ? What are the relevant techniques and how should they be applied in relation to statistical variances ?
  • How to model/measure the 3D stress at glass surface/crack tips with resolution in the nanometer scale ?
  • What can be achieved / understood through the application of surface treatments ? Interesting surface conditioning techniques involve : induction of residual stresses, densification, hydrophobicity, interaction with wet chemistry (acids, bases, slurries), plasma, mechanical abrasion, polishing treatment, organic contamination.
  • How do these treatments affect strength, but also other important properties for specific applications, such as optical and electrical properties ?
  • What can be learnt through existing and future atomistic simulations ?
  • What are the related challenges and problems ?
  • What is the time frame to overcome these issues ?
  • What are the markets to be addressed and related volumes ?
