7. Reaching the yield point of glasses with X-ray irradiation

Invited Speaker

A solid loaded beyond the yield stress loses its elastic properties and becomes plastic. From a microscopic point of view, this corresponds to the condition where plastic regions become so densely packed to give rise to system-spanning structures [1]. This limit for glasses is abrupt, which makes experimental investigations challenging: Brittle glasses exhibit mechanical failure at yield and...
