Elastic deformation returns to it's original shape after a strain is applied.
Plastic deformation returns to a deformed shape after a strain is applied. The material's molecular bonds are strained to the point of fracture, making it not possible to return to the same state.
Elastic deformation will return to its original shape. Plastic deformation is when you alter the original form. To understand more on this subject you might investigate failure analysis literature. Lots of good stuff there ratchet marks, beach marks, reverse bending etc...
I believe the U.S. metallurgical society has the best reference material on this subject.
A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape, is called elastic deformation. In other words, elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed.
Examples would be the loading of a bridge or building support beam where the loads remain within the original design parameters, or the use of a safety pin where when it is opened it returns to it's unloaded shape.
When the stress is sufficient to permanently deform the metal, it is called plastic deformation.
Examples would be the building support beams for the twin towers, where the heat generated by the fires decreased the strength of the steel and allowed it to deform plastically, or the loads that are applied to a section of electrical conduit or mechanical piping in order to bend them into a specific shape.
in elastic def. , the material returns to its original shape once force is removed. in plastic, the deformation is permanent and the material doesn't return to its original shape
the elastic deformation happens in yield pointand elastic deformation back to original size but plastic deformation will not back tto original size.

What is cold plastic deformation?
it is deformation below recrystalization temperature.
Why plastic deformation important in metal not in ceramics?
Plastic deformation in metal causes it to change shape, usually under stress such as a spinning turbine vane. Ceramics cannot deform, they are too hard and would shatter.
Strain energy definitions?
Strain energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy. Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable. A spring is an example of a storage device for strain energy.
A test specimen is stressed beyond the yield point and is then unloaded its yield point will be?
increased...because the specimen is strain hardened due to plastic deformation.
How are hardness and tensile strength related?
There are tables that give you the Tensile Strength based on a Rockwell Hardness test of a specimen of metal. For example: Rc of 54 is a Steel of TSU = 300,000 psi. Google the internet for Rockwell Hardness Table.
Difference bw elastic and plastic torsion?
after the removal of load if the object regains its original position is called elastic deformation ....If the object cant regain its original position even after the removal of applied load is called plastic deformation...
What is difference between elastic and elastic plastic analysis how can one determine wether its elastic analysis or elastic plastic analysis in ANSYS?

What is proportional strength?
When a material deforms, it does so in several stages. The first stage, called the elastic region of deformation, is linear in nature and not permanent. A stress can be applied, and once it's removed, the material will regain all of the deformation. The second stage, plastic deformation, is permanent. A material that has been stressed into the plastic region will regain the elastic deformation, but will permanently maintain the plastic.The proportional strength is the point at which plastic deformation begins.
What is it called when rocks bend instead of breaking?
Plastic deformation, either elastic or ductile.
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 is the effect of springback concept on plastic deformation?
Springback means Recovered elastic strain on material after the load is removed.
What is an elastic perfectly plastic material?
HI!!!!check out my answer....The difference between the two is....The plastic deformation will occur where pressures are relatively high and the strain rate relatively low. During plastic deformation, the materials flow and changes in shape will be permanent. While,The elastic deformation will change shape in response to a stress, then snap back into it's original shape if the stress is removed. (in other words, the strain is recoverable)IN short word...THE PLASTIC DEFORMATION ARE PERMANENT AND THE ELASTIC DEFORMATION WILL GO BACK TO ITS ORIGINAL SHAPE.ROCEL TADINA1- newton
Why a stress-strain curve usually has two segments.?
Elastic - Plastic Deformation Ranges. Before and after yield point.
What is internal plastic flow?
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.
What happens during elastic deformation for drugs?
Elastic deformation occurs when an opposing force is applied to the drug after particle rearrangement (i.e. the initial repacking of the particles). If the force is released before the yield point is reached, the particles of the drug will return to their original shape. However, if the force goes beyond the yield point, the powder will undergo plastic deformation or brittle fracture.
What has the author Kazuaki Aramaki written?
Kazuaki Aramaki has written: 'Elastic-plastic finite-element analysis of three-dimensional deformation in flat rolling'
Are matals normally used in their elastic or plastic range?
ELASTIC!@!!!! No offense but if you know what plastic and elastic deformation is you should know that once a metal enters its plastic range it cannot return to its original length. You should also realize that each successive loading cycle will eventually cause the metal to fail. An example of this is bending a paper clip back and forth until it breaks.
