Explain stress strain curve,

Question

Accepted Answer

Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.

Stress strain curve is a graphical representation of the relationship between stress and strain in a material.
It typically consists of a linear elastic region, a yield point, a plastic region, and a fracture point.
The slope of the curve in the elastic region is the material's Young's modulus.
The yield point indicates the stress at which the material begins to deform plastically.
The ultimate tensile strength is the maximum stress the material can withstand before failure.
Examples of stress strain curves include those for steel, aluminum, and rubber.
Different materials exhibit different stress strain curve shapes based on their properties.
