Fracture Physics and Crack Propagation

24.06.2019

Fracture physics, a field of study in materials science, works on understanding how and why things break by quantifying and analyzing fracture surface topography. Scientists can reconstruct the history of a crack and determine the [...]

Friction and Wear: From Elementary Mechanisms to Macroscopic Behavior

23.09.2019

In the last 25 years, the global trend to miniaturization has raised interest in frictional processes on the micro and nano scale and facilitated appearance of nanotribology as a new branch of research. Soon it [...]
Droplet friction is similar to solid friction

21.11.2017

Researchers of the Max Planck Institute for Polymer Research have investigated friction of liquid droplets on surfaces. A larger force is needed to set in motion stationary droplets than to keep moving droplets in motion. [...]
How to get sprayed metal coatings to stick
