What is Stress strain curve?

Stress strain curve for mild steel is a graphical representation of the relationship between stress and strain in a material. It is commonly used to characterize the mechanical behavior of materials and is essential in fields such as materials science, engineering, and physics.

The stress strain curve is typically obtained through a tensile test, where a specimen of the material is subjected to an increasing axial load (tensile force) until it reaches failure.

During the test, the applied load and the resulting deformation (strain) are measured.

The stress (σ) is defined as the force (F) applied to the specimen divided by the cross-sectional area (A) of the specimen:

σ = F / A

The strain (ε) is defined as the change in length (∆L) of the specimen divided by its original length (L):

ε = ∆L / L
