What is meant by elastic deformation?
: deformation that disappears upon removal of the external forces causing the alteration and the stress associated with it.
What’s the difference between plastic and elastic deformation?
When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation. When the material goes back to its original form, that’s elastic deformation.
What is elastic deformation and plastic deformation of material?
This change in shape is called deformation. 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. When the stress is sufficient to permanently deform the metal, it is called plastic deformation.
What is difference between elasticity and plasticity?
Elasticity is the property of a body to recover its original configuration (shape and size) when you remove the deforming forces. Plasticity is the property of a body to lose its property of elasticity and acquire a permanent deformation on the removal of deforming force.
What does high elastic deformation mean?
đź““ High School Level. noun Physics. the temporary change in length, volume, or shape produced in an elastic substance by a stress that is less than the elastic limit of the substance.
Who described elastic deformation?
Elastic deformation in metals commonly occurs by (small) changes in the shape of the atomic lattice (mainly by shear). Such elastic deformation is linear and therefore obeys the Hooke’s law, which allows the determination of Young’s modulus (in this chapter simply referred to as “elastic modulus”).
What is an example of elastic deformation?
Elastic deformation involves the temporary stretching or bending of bonds between atoms. For example, when bending a steel sheet, the bonds are bent or stretched only a few percent but the atoms do not slip past each other. Elastic deformation can be caused by applying shear forces or tension / compression stress.
How do you identify plastic deformation?
The plastic strain is obtained by subtracting the elastic strain, defined as the value of true stress divided by the Young’s modulus, from the value of total strain (see Figure 1).
What is an example of plastic deformation?
An example of a material with a large plastic deformation range is wet chewing gum, which can be stretched to dozens of times its original length. Under tensile stress, plastic deformation is characterized by a strain hardening region and a necking region and finally, fracture (also called rupture).
What is the reason of elastic deformation?
Elastic deformation can be caused by applying shear forces or tension / compression stress. In contrast, plastic deformation occurs when these stresses are sufficient to permanently deform the metal. In plastic deformation, breaking of bonds is caused by the dislocation of atoms.
What causes elastic deformation?
What’s the difference between plastic deformation and elastic deformation?
The elastic region shows the extent to which the elastic deformation takes place. After the elastic limit, the material will undergo plastic deformation which is a permanent deformation. Plastic deformation is the permanent deformation or change in the shape of a solid body without fracture under the action of a sustained force.
How is the elastic deformation of a solid reversible?
The elastic deformation of a solid is a reversible process, when the applied stress is removed the solid returns to its original state. When the plot of stress versus strain is linear, the system is said to be in the elastic state. However, when the stress is high the plot passes a small jump on the axes.
Is the response to stress elastic or plastic?
The response is highly dependent on the chemical bond type of the substance. Deformations can be elastic or plastic based on what happens after the stress is released. Elastic deformation is the deformation that disappears upon removal of the external forces causing the alteration and the stress associated with it.
How are chemical bonds affected by elastic deformation?
If the chemical bonds are able to withstand a high stress by deforming without breakage, that substance can undergo elastic deformation. In order to fulfil this need, chemical bonds should stretch or bend when a stress is applied to the substance. The stretching and bending of chemical bonds should be temporary.
