Measurement Method of Static Friction by a Piezoelectric Impact Drive Mechanism
Tribology Online, 2008 The coefficient of static friction is one of the basic factors of actuator performance; it influences the operational characteristics of actuators. In this present study we focus on the dependence of the coefficient of static friction on the time of ...

Journal of Manufacturing and Materials Processing, 2022 The coefficient of friction (COF) is an important parameter for mechanical engineers to consider when designing frictional connections. Previous work has shown that a surface microstructuring of the harder friction partner leads to a significant increase

Frictional Anisotropy of 3D-Printed Fault Surfaces
Frontiers in Earth Science, 2021 The surface morphology of faults controls the spatial anisotropy of their frictional properties and hence their mechanical stability. Such anisotropy is only rarely studied in seismology models of fault slip, although it might be paramount to understand ...
