Question

Explain with examples elastic plastic and brittle materials

Answer 1

Hi there

In reality, many materials that undergo large elastic and plastic deformations, such as steel, are able to absorb stresses that would cause brittle materials, such as glass, with minimal plastic deformation ranges, to break.


Thank You

Answer 2

Hey dude,
Let me answer this question.

Brittle:
Brittle material breaks while little to no energy is absorbed when stressed. The material fractures with no plastic deformation. The material in the figure below marked with (a) shows what a brittle material will look like after pulling on a cylinder of that material. Typically, there will be a large audible snap sound when the brittle material breaks. A brittle material is also known as a material having low ductility. A stress-strain curve for brittle and ductile materials is shown in the figure below. We will talk more about ductile materials in the next section.
Example:
• your nails can be brittle at some times
• cast iron
• concrete, and some glass ... 

Hope it helps.
Thankyou!
