Surface mechanics

For all functionalized glass products, mechanical requirements are crucial for their viability: stiffness, durability, resistance. What is the impact of these surface modifications and thin coatings on the surface mechanics of glass? This can be assessed through specific experimental tools and adequate modelling, so that one may eventually limit the additional weakness or enhance the mechanical improvements resulting from the functionalising coatings.
