Stress strain diagram

Question

Accepted Answer

Stress strain diagram shows the relationship between stress and strain in a material.

Stress strain diagram is a graphical representation of the relationship between stress (force per unit area) and strain (deformation) in a material.
It helps in understanding the material's mechanical properties such as elasticity, yield strength, ultimate tensile strength, and toughness.
The diagram typically consists of a linear elastic region, a yield point, a plastic deformation region, and a fracture point.
Different materials exhibit different stress strain curves based on their composition and structure.
For example, brittle materials like ceramics have a steep curve with little deformation before fracture, while ductile materials like metals have a more gradual curve with significant deformation before failure.
