Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.

What is the difference between plastic and basal flow?
Plastic flow occurs only on the surface of a glacier while basal slidingbasal slidingBasal sliding is the act of a glacier sliding over the bed due to meltwater under the ice acting as a lubricant. This movement very much depends on the temperature of the area, the slope of the glacier, the bed roughness, the amount of meltwater from the glacier, and the glacier's size.https://en.wikipedia.org › wiki › Basal_slidingBasal sliding - Wikipedia occurs along the base and sides.
Why does plastic flow only occur between 50 m of ice?
Why does plastic flow only occur below 50 meters of ice? It takes the weight of that much ice to cause the plastic flow.
What is plastic flow in soil?
Within a certain moisture range, the tension effects of the water films between the oriented plate-like colloidal particles, which impart to the soil its cohesion phenomenon, enable the soil to be molded into any deformed shape. This moisture range corresponds to the range of plasticity of a soil.

What is plastic flow in glaciers?
Basal sliding and plastic flow. This process is called basal sliding. In addition to basal sliding, which slowly moves the glacier downslope as a unit, plastic flow causes glacial ice buried underneath more than about 50 meters to move like a slow‐moving, plastic stream.
What is plastic flow rule?
The flow rule describes the interconnection between the next plastic strain increment at a stress state for a deformed material point. This relation reminds us of the stress‐strain relation for a viscos fluid and uses the principle of a plastic potential surface g.
What are plastic flows?
Plastic flow is a rheological phenomenon in which flowing behavior of the material occurs after the applied stress reaches a critical value (yield).

What causes plastic flow to occur?
Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
How does plastic flow work?
The material gives the impression of flowing under the applied loads, and this flow is plastic, since, if the load is removed, the specimen retains its deformation. Eventually, plastic flow will come to an end: deformation will ultimately tend to concentrate in one area, which will break.
Understanding The Mechanism Of Plastic Deformation
What does plastic flow mean?
plastic flow in American English noun. deformation of a material that remains rigid under stresses of less than a certain intensity but that behaves under severer stresses approximately as a Newtonian fluid. Also called: plastic deformation.
What is plastic flow glacier?
Basal sliding and plastic flow. This process is called basal sliding. In addition to basal sliding, which slowly moves the glacier downslope as a unit, plastic flow causes glacial ice buried underneath more than about 50 meters to move like a slow‐moving, plastic stream.
