Question

Explain stress-strain curve

Answer 1

Stress-strain curve typical of a low carbon steel.
For broader coverage of this topic, see Stress–strain analysis.
In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength.

Answer 2

Answer:

A stress strain diagram or stress strain curve is used to illustrate the relationship between a material's stress and strain. A stress strain curve can be constructed from data obtained in any mechanical test where load is applied to a material and continuous measurements of stress and strain are made simultaneously.
