A photograph of the fracture surface in a silicone model, across both fracture planes, shows that the crack profile has a certain curvature

Secrets, cracks and fractures

It turns out that the shorter a crack in brittle materials - the more resistant they are to it, which can help in the design and use of applications that are based on brittle materials

This research, recently carried out by Prof. Jay Feinberg and Neri Berman from the Rekh Institute of Physics, was published in the prestigious journal Physical Review Letters. The study revealed, for the first time, the behavior in the immediate vicinity of the crack tip.
A sheet of water is created when a jet hits a target. In the picture, a sheet of water is created when water flowing from the faucet hits the spoon above the kitchen sink. This sheet will eventually break down into droplets; While sheets of liquid may seem like an abstract image, the physics that govern the process are relevant to fields ranging from fuel injection to irrigation.
