Explain what is meant by plastic deformation

WebDec 7, 2024 · noun ( Mechanical engineering: Materials) In plastic deformation a material changes shape when a stress is applied to it and does not go back to its original state when the stress is removed. Plastic deformation needs to occur in any metal forming operation. WebThe atomic structure affects the properties of the materials, their behavior, and their applications. It also affects the type of bonds which holds the materials together. It also helps us to differentiate between the type and class of material such as amorphous or crystalline, metals, semiconductors, ceramics, and polymers. With the help of ...

Web(ii) Region of Uniform Plastic Deformation: In the range of stresses between yield stress, S 0, and the beginning of the necking (before nearly the straight line portion begins), the plastic deformation occurs uniformly. (iii) Region of Non-Uniform Plastic Deformation: WebNov 8, 2024 · Elastic and plastic deformation is due to the action of load on the body. These deformations in the structure are observed due to particles' movement. These deformations are induced due to the action of stress in the structure.
