People Also Ask about

What is the point at which plastic deformation occurs?

'Yield point' is the point at which the material fails to return to its original position. If the material is loaded to a greater amount than the yield point, then deformation will occur.

What is plastic deformation at the atomic level?

In this process, a change occurs not only in the visible shape and size, but also at the atomic level in the interior of the material. Plastic deformation of a metal occurs by slipping of atoms on specific planes of a crystal. This slipping of atoms does not occur at any one time over the entire crystal plane.

What is the process by which plastic deformation occurs?

The process of plastic deformation produced by dislocation motion is referred to as "slip deformation." This occurs when dislocations move through the atomic lattice of a material in response to shear stress, resulting in a permanent change in shape.

What is plastic deformation of a material?

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 plastic deformation and what is going on in the material at the atomic level when this occurs?

As discussed in the section on crystal defects, plastic deformation involves the breaking of a limited number of atomic bonds by the movement of dislocations. Recall that the force needed to break the bonds of all the atoms in a crystal plane all at once is very great.

What causes plastic deformation in polymers?

Under an applied stress these polymers plastically deform past their yield strength in a manner known as cold drawing. Cold drawing involves viscous flow where the chains slide past one another. Initially, the chains may be highly tangled but the applied stress forces them to elongate and align in a single direction.
