Vibration perturbs the recurrence period of inelastic stress increase before the failure of major events and induces small-amplitude stick–slip events. In many cases one or more small stick–slip ...

Researchers have uncovered key features of the dynamics of "stick-slip," a form of jerky motion responsible for squeaks and squeals in phenomena from door hinges to shifting tectonic plates. In this ...

Coating the inside of glass microtubes with a polymer hydrogel material dramatically alters the way capillary forces draw water into the tiny structures, researchers have found. The discovery could ...

Back in the 1980s, Pacific Bearing Co. (PBC) invented and commercialized plain bearings, which were sized to be interchangeable with linear ball bearings. Plain bearings worked very well in certain ...
