This stress-strain relationship is known as Hooke’s Law, and in this region, the slope of the stress-strain curve is referred to as the modulus of elasticity (aka Young’s modulus), denoted E. The modulus of elasticity is essentially a measure of stiffness and is one of the factors used to calculate a material’s deflection under load. The internal resistance force per unit area acting on a material or intensity of the forces distributed over a given section is called the stress at a point.. Differences between Stress and Strain: The force applied to object, the object gets displaced that is stress and Strain is the change in the form or shape of the object or physical body on which stress is applied.
