(Aarhus University) By removing material via specially designed cuts in a glasslike material, researchers from Aarhus University, Denmark, and the University of Pennsylvania in the US have changed the mechanical properties of the material. The cuts make it possible for the material to “fracture by design” which significantly increases the component’s resistance to cracks and fracture in addition to being lighter and more flexible.
