I bend but do not break: Alumina glass films flex and stretch without fracturing

By Lisa McDonald / January 10, 2020

An oxide glass that can plastically deform under unconfined loading conditions would be a big asset in potential applications. An international team of researchers found alumina glass films exhibit such an ability.

Disorderly conduct: Insight into materials failure could lead to glasses that are less likely to break

By April Gocha / December 5, 2017

An interdisciplinary group of scientists at the University of Pennsylvania have harnessed intense computation, data, and modeling power to determine how disordered solids fail, an understanding that could help engineer custom materials, such as glass that is less likely to break.
