Until a metal reaches its elastic limit, it is undergoing elastic deformation. This means that the metal will regain its original dimensions when unloaded. Upon exceeding the elastic limit, the metal will become plastic and will not regain its original dimensions.
A metal undergoes plastic flow when it experiences large deformations while loaded in the plastic region.
Internal plastic flow refers to the deformation of a material without fractures or cracks occurring. It typically happens in ductile materials under high stress and temperature conditions, causing the material to permanently change shape without breaking. This process is commonly observed in metal forming and forging operations.

Why does the charge flow through the copper wire but not the plastic coating that covers it?
The copper wire is a conductor that allows electric charges to flow through it easily due to its free-moving electrons. The plastic coating, on the other hand, is an insulator that does not allow electric charges to flow through it because its electrons are tightly bound to their atoms, preventing the flow of electricity.
Does a plastic kettle handle prevent or helps heat flow?
Plastic is a good insulator of heat, meaning heat can't flow through it very well. So a plastic handle on a kettle doesn't conduct heat through it and this means you don't get burnt when handling it.
Is a plastic bottle a conductor?
No, plastic bottles are typically not conductors of electricity. They are insulators, meaning they do not easily allow the flow of electrical current.
What substance blocks the flow of electricity?
Insulators, such as rubber or plastic, are substances that block the flow of electricity by preventing the movement of electrons. These materials have high electrical resistance, which hinders the flow of electric current through them.
Is plastic viscosity or not viscosity?
Plastic viscosity is a type of viscosity that represents the resistance to flow of a material before it starts to deform. It is different from the more common dynamic viscosity, which represents the resistance to flow of a material once it is already deforming.
How do the processes of basal slip and internal plastic flow differ?
Basal slip involves the movement of crystal planes over each other in a preferred direction, usually parallel to the basal plane, allowing for plastic deformation in materials like metals. Internal plastic flow refers to the movement of dislocations within the material, leading to permanent deformation without fracture. While basal slip is more common in crystalline materials with well-defined crystal structures, internal plastic flow can occur in various materials with defects and dislocations.
What part of a glacier moves fastest when glacier moves by internal plastic flow?
The center or axis of a glacier generally moves the fastest when the glacier is moving by internal plastic flow. This is due to the greater pressure and thickness of ice at the center, causing it to flow more readily than the slower moving edges and margins of the glacier.
What are 3 types of glacier movement?
Three types of glacier movement are basal sliding, internal deformation, and flow. Basal sliding occurs when the glacier moves over a layer of meltwater at its base. Internal deformation involves the slow movement of ice crystals within the glacier. Flow refers to the overall movement of the glacier downslope due to gravity.
What part of glacier moves fastest when the glacier moves by internal plastic flow?
The central part of the glacier moves fastest than its edges as it is thickest from the center.
Will electricity flow through a plastic comb?
No, electricity will not flow through a plastic comb because plastic is an insulator and does not conduct electricity.
What does electricity not flow through?
Plastic
What deforms by plastic flow?
asthenosphere
Why can't electricity flow through plastic?
Because metal and plastic arent the same materials so metal goes with the flow through static electricity but plastic cant.
What is a substance that has no internal resistance to flow?
its a liquid
What is a rock that deforms like a piece of molded clay called?
A rock that deforms like molded clay is called a plastic rock. These rocks can be easily reshaped due to the internal flow of their minerals. Examples of plastic rocks include shale, claystone, and serpentinite.
What does electricity not flow through well?
Plastic
What causes plastic flow to?
High pressure
