Origin of sliding friction: role of lattice trapping The friction force acting on a block sliding on a substrate is usually nearly velocity independent unless the sliding speed is so low that thermal activation is […]
Most of the natural or engineered surfaces are not perfect, meaning they are rough. The surface roughness was found across many scales: from atomic to tectonic. The earth looks smooth from space, but someone standing […]
The famous picture of transportation of an Egyptian statue to the grave of Tehuti-Hetep, El-Bersheh indicates that the concept of lubrication was already known to ancient Egyptians. The picture below shows how the slaves are […]
Recent research (https://doi.org/10.1007/s40544-017-0183-5) has shown that about 23% of the world’s total energy consumption comes from the tribological contacts (moving parts subject to friction and wear, such as bearings, gears, etc.). This energy is lost, […]
Hadrien Rattez, a research scientist in civil and environmental engineering at Duke University and Manolis Veveakis, an assistant professor of civil and environmental engineering at Duke University, have joined forces to create a model, which […]
Heriberto Perez, a researcher at the UPV/EHU’s Faculty of Engineering-Bilbao, has developed behavior models able to predict the future deterioration of roads. The models focus on two different aspects, the international roughness index (IRI) and […]
Every child has experienced the magic of static electricity. Eyes light up as he or she performs magic by rubbing a balloon against his or her hair and the balloon then sticks to the wall. […]
A recent work by the researchers from Leibniz University Hannover presents a 3-D framework for simulation of contact-driven-fracture processes (like abrasive wear) in filled elastomers. Modeling of material removal processes, like wear, to this day […]
Rubble ice is a jumble of ice fragments or small pieces of ice, which cover an expansive area with no particular pattern or order. Areas in the Arctic and Antarctica have large expanses of rubble […]

Plate tectonics explains the features and movement of the Earth’s surface both in the present and in the past. It is the theory that the outer shell of Earth is divided into many plates (including […]
