stress strain curve in detail

Question

Accepted Answer

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

Stress strain curve is a graphical representation of the relationship between stress (force per unit area) and strain (deformation) in a material.
It typically consists of a linear elastic region, a yield point, a plastic deformation region, and ultimately failure.
The slope of the curve in the elastic region is the material's Young's Modulus, which represents its stiffness.
The yield point marks the transition from elastic to plastic deformation, where the material undergoes permanent deformation.
Different materials exhibit different stress strain curves based on their properties and behavior under load.
For example, brittle materials like ceramics have a steep curve with little plastic deformation, while ductile materials like metals have a more gradual curve with significant plastic deformation before failure.
