Indentation and scratching of glass: Load, composition and temperature effects

International audienceThe response of glass to mechanical contact has been the subject of numerous publications. However, most of the investigations were dedicated to standard window glasses, although there is a need for the characterization of functional glasses such as chalcogenide glasses and of newly developed structural glasses, including oxynitride and oxycarbide glasses. Besides, most investigators focused on the phenomenology and on the mechanics of contact damage and the incidences of the glass composition, the environment and the temperatures were little studied and thus remain poorly understood
