(2017-06-16)Experimental investigation of dependence of sliding-friction on velocity is necessary to understand the physics of earthquakes. Velocity-dependent friction is ideally studied in experiments by imposing step-wise changes ...
-
(2012-10-19)Friction, wear, and lubrication have direct influence on performance, reliability, and service life of mechanical systems with moving components. The useful life of these systems and their efficiency can be improved by ...
-
(2012-02-14)The San Andreas Fault (SAF) near Parkfield, CA moves by a combination of aseismic creep and micro-earthquake slip. Measurements of in situ stress orientation, stress magnitude, and heat flow are incompatible with an ...
-
(Texas A&M University, 2005-11-01)Motion control systems are usually designed to track trajectories and/or regulate about a desired point. Most of the other objectives, like minimizing the tracking time or minimizing the energy expended, are secondary which ...
-
(2014-12-02)Groundwater wells can have extreme pressure buildup when injecting and extreme pressure drawdown when extracting. Greater wellbore contact with the aquifer minimizes pressure buildup and pressure drawdown. Aquifers are ...
-
(2012-07-16)The objective of current study was to numerically investigate the flow and heat transfer characteristics in a stationary one pass rectangular channel (AR=4:1) with circular and elliptical pin fin arrays. Two types of ...
-
(2022-02-16)The “size effect” phenomenon in metal cutting – the substantial increase of the specific cutting energy with the decreasing chip size – is systematically studied. An instrumented ultramicrotome is applied to achieve ...
-
(2019-04-15)Coastlines often have to be maintained through engineering practices to preserve coastal communities and environments and to limit damage from flooding during storm impact. As the expenses of coastal upkeep increase due ...
-
(2010-01-16)In the last 35 years, several researchers have proposed, developed and tested different friction devices for seismic control of structures. Their research has demonstrated that such devices are simple, economical, practical, ...
-
(2018-05-04)Frictional properties of fiber assemblies from different cotton varieties were investigated using a sliding friction tester. Results indicated that frictional characteristics of cotton fibers varied significantly among ...
-
(2020-04-08)Comprehensive evaluation on the influence of select commercial friction-modifying additives on the tribological performance of water-based mud will enable more widespread usage of waterbased mud (WBM) with confidence as a ...
-
(2005-08-01)Two methods are proposed for the computation of friction factors of commercial pipes. The first method applies the mean value of the zero velocity point (MZVP) to a theoretical friction factor equation, and the other ...
-
(2015-09-22)Understanding and controlling friction, adhesion and wear is critical for the continued growth and utilization of emerging nanotechnologies such as micro- and nano-electromechanical systems devices (NEMS/MEMS). The challenge ...
