Question

In many ductile materials, deformation does not remain uniform. At some point, one region deforms more than others and a large local decrease in the cross-sectional area occurs. This phenomenon is known as ___

Answer 1

Answer:

Necking

Explanation:

Necking is a mode of tensile deformation in material science and engineering. This is a phenomenon in which a large strain can be disproportionately been localized in a small area of materials. Slowly there is the reduction of the cross-sectional area which names its neck.

The local strain there in the neck is local which is associated with the yielding. This is the form of the deformation of the plastic that is associated with the ductile materials. The neck is the prominent area of the exclusive location. This phenomenon is called necking.
