Most of our understanding of earthquake rupture comes from interpretation of strongground-motion seismograms; however, near-rupture-tip fields of stress and particle motions are difficult to resolve. In particular, the decay of frictional resistance from a peak value at the leading tip of the rupture to a residual kinetic value and subsequent healing characterizes the earthquake process, yet th...

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 ...

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 ...

The brittle-viscous transition in the lithosphere occurs a region where many large earthquakes nucleate. To study this transition, we sheared bimineralic aggregates with varying ratio of quartz and potassium feldspar. We deformed samples solid-medium deformation apparatus at temperature, T = 750°C pressure, Pc 800 MPa under either constant displacement rate or load boundary conditions. Under ra...
