[1] We compare 2-D, quasi-static earthquake nucleation on rate-and-state faults under both ‘‘aging’’ and ‘‘slip’’ versions of the state evolution law. For both versions mature nucleation zones exhibit 2 primary regimes of growth: Well above and slightly above steady state, corresponding respectively to larger and smaller fault weakening rates. Well above steady state, aging-law nucleation takes...

This study examines how lower extremity fatigue of the quadriceps alters gait variables related to slip propensity. Sixteen healthy young adults were recruited to walk across vinyl floor surfaces in states of fatigue and no fatigue. Kinematic and kinetic data were collected using a three-dimensional motion analysis system and force plates. The results indicated a significant increase in both th...

We intend to study a particle fluid suspension model for blood flow through an axially asymmetric but radially symmetric mild stenosis in the annular region of an inclined tapered artery and a co-axial catheter in a suitable flow geometry has been considered to investigate the influence of velocity slip at the stenotic wall as well as hematocrit, shape parameter. The model also includes the tap...

[1] Earthquake nucleation requires reduction of frictional strength = ( p) with slip or slip rate, where , n, and p are the friction coefficient, normal stress, and fluid pressure, respectively. For rate state at fixed ( p), instabilities can occur when d ss/dv < 0, where ss is the steady state friction and v is slip rate. Shear heating increases p and, if dilatancy and pore pressure diffusion ...

A study on the flow of non-Newtonian nanofluid between two coaxial cylinders is made. Two types of series solutions are constructed by choosing constant and variable viscosity. The effects of heat transfer analysis on nanoparticles in the presence of magnetohydrodynamics, porosity and partial slip are also examined. To drive the solutions of nonlinear boundary value problems, we have used a rec...

The objective of this paper is to analyze the effect of radiative heat and mass transfer on unsteady natural convection couette flow of a viscous incompressible fluid in the slip flow regime in presence of variable suction and radiative heat source. The governing equations of the flow field are solved employing perturbation technique and the expressions for the velocity, temperature, concentrat...

Incorporating the velocity slip effect of the gas flow at the solid boundary, the performance and dynamic response of a micro gas-bearing-rotor system are investigated in this paper. For the characteristic length scale of the micro gas bearing, the gas flow in the bearing resides in the slip regime rather than in the continuum regime. The modified Reynolds equations of different slip models are...

mathematical model is developed for the time-dependent circular tube flow of compressible olymeric liquids subject to pressure-dependent slip at the wall and applied to a poly dimethyl iloxane PDMS . The parameters of pressure-dependent wall slip velocity and shear viscosity of he PDMS were determined using combinations of small-amplitude oscillatory shear, steady orsional and squeeze flows and...

Modern concepts of electrified drive trains for off-road vehicles allow for some new possibilities for control strategies. When considering traction efficiency, the most controllable factor is wheel-slippage. Many existing slip control systems use a certain threshold value of slip as reference, for example for farm tractors, electrohydraulic hitch control system (EHC) controls the implement, wh...

It is known that a boundary slip velocity starts to play an important role when the length scale over which the fluid velocity changes approaches the slip length, i.e., when the fluid is highly confined, for example, fluid flow through porous rock or blood vessel capillaries. Zhu and Granick [Phys. Rev. Lett. 87, 096105 (2001)] have recently experimentally established the existence of a boundar...
