Question

the slope of the stress-strain curve in the elastic deformation region is?​

Answer 1

Young's modulus.

The slope of the stress-strain curve in the elastic deformation region is the modulus of elasticity, which is known as Young's modulus. It represents the stiffness of the material-resistance to elastic strain. The description of Hooke's law can also be found from the slope.

Answer 2

The slope of the stress-strain curve in the elastic deformation region is Elastic modulus

Explanation:

The relationship between stress and strain is given by the following equation:

$E\;=\;\frac\sigma\varepsilon$

where

$E$ is the constant of proportionality, known as the Elastic modulus or Young's modulus

σ is the stress

ε is the strain

• When a graph is plotted on the association between stress and strain it is called the stress-strain curve.
• This signifies the change in stress with the change in strain.
