Plastic flow definition geology
Webinitial plastic flow and hardening, the force-displacement curve decreases, as in some soils; the material is said to be softening. If the specimen is unloaded from a plastic state (B) it will return along the path BC shown, parallel to the original elastic line. This is elastic recovery. The strain which remains upon unloading is the permanent ...

WebDebris flows are fast-moving landslides that are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. They occur in a wide variety of environments throughout the world, including all 50 states and U.S. Territories. Debris flows generally occur during periods of ... WebThe literal meaning of the word isostasy is “equal standstill,” but the importance behind it is the principle that Earth’s crust is floating on the mantle, like a raft floating in the water, rather than resting on the mantle like a raft sitting on the ground. The relationship between the crust and the mantle is illustrated in Figure 9.16.
WebIn 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. WebDebris flows typically originate in semi-arid areas where thick soils or surficial deposits begin moving as a landslide and become more mobilized as they move into a stream channel. Eventually, they flow like wet concrete. Many alluvial fans include areas covered by prehistoric debris-flow deposits and hence are susceptible to continued activity.
Webplasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture ( see yield point). WebJan 1, 2014 · where k is the yield strength, μ b is the Bingham viscosity, and ε s rate of shear strain. The expression tells us that above the yield strength k the flow behaves viscous and has a linear viscosity called the Bingham or plastic viscosity. The apparent viscosity may be shear stress related and deformation above the yield strength is in such case non …
WebFeb 6, 2024 · This is referred to as recoverable strain. This elastic deformation is not recorded in the rock record. The deformation recorded in the rocks occurs when the rocks break (fail) or flows viscously (a type of crystal-scale failure) or plastically (also a crystal-scale failure process).
