In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are ...
So The Polar Express is at best disconcerting, and at worst, a wee bit horrifying". [65] The term "eerie" was used by reviewers Kurt Loder [66] and Manohla Dargis, [67] among others. Newsday reviewer John Anderson called the movie's characters "creepy" and "dead-eyed", and wrote that "The Polar Express is a zombie train". [68]
Grain size and fabric orientation are known to influence the creep of glacial ice, but are dynamic properties which also evolve with the stress regime and are not simple to capture in a model. [ 20 ] The Glen-Nye flow law also does not render the full range of ice response to stress, including elastic deformation , fracture mechanics (i.e ...
Talus cones produced by mass moving, north shore of Isfjord, Svalbard, Norway Mass wasting at Palo Duro Canyon, West Texas (2002) A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.
Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.
The equation of motion for Stokes flow can be obtained by linearizing the steady state Navier–Stokes equations.The inertial forces are assumed to be negligible in comparison to the viscous forces, and eliminating the inertial terms of the momentum balance in the Navier–Stokes equations reduces it to the momentum balance in the Stokes equations: [1]
Ice creep; Frost creep [A] Gelifluction; Plug-like flow; Slow solifluction acts much slower than some geochemical fluxes or than other erosion processes. [1] The relatively low rates at which solifluction operates contrast with its occurrence over wide mountain areas and periglaciated lowlands.
Salix polaris, the polar willow, is a species of willow with a circumpolar distribution in the high arctic tundra, extending north to the limits of land, and south of the Arctic in the mountains of Norway, the northern Ural Mountains, the northern Altay Mountains, Kamchatka, and British Columbia, Canada.
