Diamond coatings help reduce friction and wear on tools, bearings, and seals. Lubricating diamond with water considerably lowers friction. The reasons for this are not yet fully understood. The ...

Technological limitations have made studying friction on the atomic scale difficult, but researchers have now made advances in that quest on two fronts. By speeding up a real atomic force microscope ...

Excessive resistance against the movement of adjacent plies, or ply-ply friction, can lead to process-induced defects during hot press forming of thermoplastic composite laminates. To avoid the ...

Friction is a pervasive nonlinearity in mechanical systems, arising at interfaces from the microscale asperities of surfaces and manifesting in macroscopic performance degradation, wear and control ...

Many less-experienced users of finite-element-analysis (FEA) software often have no clue if the results they get are anywhere near the correct answer. To gain more confidence with FEA, it’s a good ...
