S U M M A R Y We use idealized subduction megathrust models to examine aseismic, frictional fault creep throughout the interseismic period. We consider rate-dependent and rateand state-dependent friction. When there is significant post-seismic creep surrounding locations of coseismic slip, the creep rates surrounding an asperity may be lower than the plate convergence rate late in the seismic c...

The Longmen Shan is the steepest topographic front at the India-Asia collision zone and the site of the Mw 7.9 Wenchuan earthquake. Here to explain the interseismic GPS velocities across the greater Longmen Shan region, we develop a boundary element model including earthquake cycle effects, topography, the westward dipping Beichuan Fault and a ∼20 km deep, shallowly dipping, detachment, inferre...

[1] We simulate 1000 years of the earthquake cycle along the San Andreas Fault System by convolving best estimates of interseismic and coseismic slip with the Green’s function for a point dislocation in an elastic plate overlying a viscoelastic half-space. Interseismic slip rate is based on long-term geological estimates while fault locking depths are derived from horizontal GPS measurements. C...

Temporal changes in seismic velocity during the earthquake cycle have the potential to illuminate physical processes associated with fault weakening and connections between the range of fault slip behaviors including slow earthquakes, tremor and low frequency earthquakes1. Laboratory and theoretical studies predict changes in seismic velocity prior to earthquake failure2, however tectonic fault...

stabilization of earth slopes with various proposed methods is one of the important concerns of geotechnical engineering. in this practice, despite numerous developments, design conservativeness and high costs of stabilization are the issues yet to be addressed. this paper not only deals with pile location optimization but also studies the effects of the pile length by using line segments slip ...

Jee et al. assert (1) that the effect we measure— what happens to a lubricant film thickness in individual slip events during intermittent stick–slip sliding (2)—was already measured long ago (3, 4), and with better resolution. We are bemused by this assertion because in the works cited (3, 4) not only is intermittent stick–slip friction, with its characteristic saw-tooth pattern, not shown or ...

this paper studied the mathematical method of flow with regard to two-phase boundary layer that created over the iced surface. based on experimental results, skin drag over the iced surface compared with this force that compute with slip condition. based on this results, for iced surface blasius equation solving at non-slip condition, can replace with solving the blasius equation with slip cond...

There is an obvious need for a technique whereby the medium surrounding an organism under microscopy can be altered without displacing the organism from the field. For example, we are interested in observing the same organisms before, during, and after exposure to various agents. Our general solution is to confine the organisms within a microchamber separated from the well of a well-slide by a ...

This paper presents a detailed finite element modeling scheme to simulate the cyclic response of RC columns considering low-cycle fatigue and bond-slip reinforcement. The includes triaxial constitutive model recently proposed in literature concrete failure under loading. For steel, commonly used uniaxial is enhanced account for bar rupture using new criterion, which has been validated with data...
