The upper layers of the bed materials are deformed by the frictional drag of the overlying ice. Unconsolidated material will act like a ball bearings and allow the glacier to move forward.

What is a deformation and what causes it?

Deformation is a change in the shape or size of a material due to stress or strain. It can be caused by external forces such as pressure, tension, or shearing forces acting on the material, leading to a rearrangement of its atomic structure. Deformation can result in a temporary change (elastic deformation) or a permanent change (plastic deformation) in the material.


What is anelastic deformation?

Anelastic deformation is a type of deformation in materials where they exhibit some degree of recovery after the stress is removed, similar to elastic deformation. However, anelastic deformation involves some permanent rearrangement of the material's structure, causing it to not return completely to its original shape. This behavior is typically seen in materials like polymers and some metals.


How many types of deformation?

There are generally three main types of deformation: elastic, plastic, and brittle. Elastic deformation occurs when a material returns to its original shape after the stress is removed. Plastic deformation involves a permanent change in shape due to applied stress, while brittle deformation leads to fracture without significant deformation. Each type responds differently to stress and strain depending on the material properties and environmental conditions.


What is an example of deformation?

In an elastic deformation, the object will return to its original shape afterwards (like tapping your arm softly with a needle, without piercing the skin). In a plastic deformation the object will first undergo elastic deformation, but then undergo a deformation that changes the shape of the material. (like tapping your arm with a needle that pierces through the skin and leaves a small wound).


What would happen if the force causing the deformation became greater?

The deformation would increase because the force increases.

Why used cast iron in lathe bed not mild steel?

Cast iron is less susceptible to deformation from applied forces from the machinery.


What kind of deformation leads to deformation?

elastic deformation


What is sub-glacial deformation?

Sub-glacial deformation refers to the mechanical processes that occur within glacier beds due to the movement of ice over sediment or bedrock. This movement can cause the bed to deform and rearrange, leading to the formation of landforms such as drumlins, eskers, and moraines underneath the glacier.


What is cold plastic deformation?

it is deformation below recrystalization temperature.


What are two kinds of deformation?

Two kinds of deformation are plastic deformation, where the material changes shape permanently due to stress, and elastic deformation, where the material returns to its original shape after stress is removed.


What is elastic deform?

Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.


What is elastic deformation?

Elastic deformation is the temporary distortion experienced by a material under stress, where the material returns to its original shape once the stress is removed. This deformation is reversible and does not cause permanent changes to the material's structure.

How do brittle objects undergo plastic deformation?

Brittle objects typically do not undergo plastic deformation due to their inability to sustain significant deformation before fracturing. Instead, brittle materials tend to fracture with minimal or no plastic deformation.


Does deformation by drawing decreases the tensile modulus?

What is the plastic deformation formula used to calculate the extent of permanent deformation in a material under stress?

The plastic deformation formula used to calculate the extent of permanent deformation in a material under stress is typically represented by the equation: ( / E), where is the strain (deformation), is the stress applied to the material, and E is the material's Young's modulus.
