The aim of this paper is to study the effect of slip velocity and shape of stenosis on non-Newtonian flow of blood through a stenosed arterial segment. Blood is modeled as Bingham-Plastic fluid in a uniform circular tube with a radially non-symmetric stenosis. The problem is investigated by a joint effort of analytical and numerical techniques. The influence of stenosis shape parameter, slip ve...

We demonstrate a rupture front focusing phenomenon at the initial stage of earthquake, which causes high slip rate pulses and therefore generates high frequency seismic waves. In this computation, we assume a pre-slip region, where stress has already lowered quasi-statically to the dynamic friction level. And due to the pre-slip, we suppose a stress concentration at the edge of pre-slip area. T...

S U M M A R Y Slip-rate function and the rupture velocity are two important parameters that are critical in understanding the physics of earthquakes. When conventional objective functions are used, the slip-rate function is not well resolved from seismic data. Here, we propose a new method to obtain the slip-rate function by utilizing the near-field phases recorded near the fault rupture. First...

The properties and behaviour of an  colony Ti-6242 alloy have been investigated at 20C utilising coupled micro-pillar stress relaxation tests and computational crystal plasticity. The -phase slip strength and intrinsic slip system strain rate sensitivity have been determined, and the -phase shown to have stronger rate sensitivity than that for the  phase. Close agreement of experimental o...

Two monuments from an 1855 cadastral survey that span the San Andreas fault in the Carrizo Plain have been right-laterally displaced 11.0 --2.5 m by the 1857 Fort Tejon earthquake and associated seismicity and afterslip. This measurement confirms that at least 9.5 --0.5 m of slip occurred along the main fault trace, as suggested by measurements of offset channels near Wallace Creek. The slip va...

We present 2D dynamic rupture models of the 2011 Tohoku-Oki earthquake based on linear slip-weakening friction. We use different types of available observations to constrain our model parameters. The distribution of stress drop is determined by the final slip distribution from slip inversions. As three groups of along-dip slip distribution are suggested by different slip inversions, we present ...

We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static fatigue. We analyze temporal properties of aftershocks in order to determine the time delay before the onset of the power law aftershock decay rate. In creep-slip and stick-slip zones, we show that...

Excavations in a playa along the 1992 rupture of the Emerson fault reveal evidence of two paleoseismic events, with only one large prehistoric rupture in the past 15 millennia. Accelerator mass spectrometer radiocarbon ages of charcoal from playa sediments and from faultscarp colluvium directly beneath the playa beds indicate that the last large prehistoric slip event occurred about 9000 ka. Tr...

This work examines the slip boundary condition by Lattice Boltzmann simulations, addresses the validity of the Navier’s hypothesis that the slip velocity is proportional to the shear rate and compares the Lattice Boltzmann simulations to the experimental results of Tretheway and Meinhart (Phys. of Fluids, 14, L9-L12). The numerical simulation models the boundary condition as the probability, P,...
