Surface Rupture of the 1857 Southern Italian Earthquake?
Terra Nova, 1998In October 1862, Robert Mallet published an extensive study of a large earthquake that occurred on 16 December 1857, 150 km southâeast of Naples. This event is one of the most destructive ever recorded in Italy. Although continental earthquakes of similar size are almost invariably associated with surface faulting, Mallet did not identify any surface ...

Rupture of thin liquid films on structured surfaces
Physical Review E, 2011We investigate stability and breakup of a thin liquid film on a solid surface under the action of disjoining pressure. The solid surface is structured by parallel grooves. Air is trapped in the grooves under the liquid film. Our mathematical model takes into account the effect of slip due to the presence of menisci separating the liquid film from the ...

Semiconductor bond rupture phenomena and surface properties
Applied Surface Science, 1996The complexities of semiconductor bond rupture processes and cleavage surfaces are becoming clarified by recent studies. The high energies released during bond breaking cause a variety of phenomena, including generation of voltages and currents, and emission of light of various wavelengths and durations. Electrical effects during cleavage of Si include

Analysis of slope considering circular rupture surface
International Journal of Geotechnical Engineering, 2016Determination of stability under seismic loading condition of soil slope is one of the important findings for geotechnical engineers. Here, in this paper, a homogeneous soil slope considering circular failure surface has been analyzed under the influence of pseudo-dynamic inertia forces and surcharge load by limit equilibrium method. The Fellenius line

Rupture of Xanthate Molecules at Copper Surfaces
Nature, 1963As part of an investigation into the mode of action of dropwise condensation promoters, an investigation has been made of the kinetics of the adsorption of OS dioctadecyl xanthate on to fused copper powder from solution in carbon tetrachloride. The procedure was to shake the reactants in a stoppered flask and follow the rate of xanthate removal by ...

Rupture and dewetting of water films on solid surfaces
Journal of Colloid and Interface Science, 2010An experimental study was conducted to observe rupture and dewetting of water films, 0.5-2mm thick, on solid surfaces. The effects of surface roughness, wettability, protrusions on surfaces, and air entrapment between films and surfaces were studied. Film thickness measurements were made and film rupture and surface dewetting photographed.

Bulletin of the Seismological Society of America, 2009
Recent ground-motion observations suggest that surface-rupturing earth- quakes generate weaker near-fault ground motion than buried earthquakes. This dif- ference is significant in the period range of 0.3-3 sec. Contributing factors to this phenomenon may include the effect of fault zone weakness at shallow depth on rup- ture dynamics and rupture ...

Anchors in sand bed: delineation of rupture surface
Ocean Engineering, 1999Abstract Anchors of very large uplift capacities are required to support offshore structures at great water depths. The capacities of plate and mushroom type anchors are generally estimated based on the shape of rupture surface. An attempt has been made in the present investigation to delineate the rupture surfaces of anchors embedded in submerged ...

Numerical Models of Translational Landslide Rupture Surface Growth
Pure and Applied Geophysics, 2000We analyze the initiation and enlargement of the rupture surface of translational landslides as a fracture phenomenon using a two-dimensional boundary-element method. Both processes are governed largely by the stress field and the pre-existing planes of weakness in a slope. Near the ground surface, the most compressive stress becomes either parallel or

Rupture and Reformation of Ultra-Thin Surface Films
Volume 4: 12th International Conference on Advanced Vehicle and Tire Technologies; 4th International Conference on Micro- and Nanosystems, 2010In lubricated contact conjunctions film ruptures close to the exit boundary. This significantly affects the load carrying capacity and can lead to direct surface interactions. Nano-scale films (several molecular diameters of the lubricant) are no exception, a fact that has been observed using ellipsometry studies for ultra-thin film conjunctions ...
