Ultrasound can reduce friction in deep drawing and thus protect tools and ... Previously, effective use of ultrasound was only possible in nearly static laboratory setups. For vibration excitation ...

This method has enabled a number of key conclusions on the mechanism of transition from static to ... and contribute in drawing the roadmap for the future studies on friction.

An 1886 drawing of Andreas Cunaeus experimenting ... the dielectric plate is first rubbed with a cloth to create a static charge through friction. This is another example of the triboelectric ...
