Explain the stress-strain curve.

Question

Accepted Answer

Stress strain curve shows the relationship between stress and strain in a material under tension.

The curve typically consists of three main regions: elastic deformation, plastic deformation, and fracture.
In the elastic region, the material returns to its original shape after the stress is removed.
Plastic deformation occurs when the material undergoes permanent deformation.
Fracture is the final stage where the material breaks.
The slope of the curve in the elastic region is the Young's Modulus, representing the material's stiffness.
The area under the curve represents the energy absorbed by the material during deformation.
