Young’s modulus (E) is the modulus of elasticity under tension or compression. In other words, it describes how stiff a material is or how readily it bends or stretches. Young’s modulus relates stress (force per unit area) to strain (proportional deformation) along an axis or line.
Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression. Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise.

Young’s modulus \(Y\) is the elastic modulus when deformation is caused by either tensile or compressive stress, and is defined by Equation \ref{12.33}. Dividing this equation by tensile strain, we obtain the expression for Young’s modulus:
Steps to Calculate Young’s Modulus. To calculate Young’s modulus of elasticity, follow these steps: 1. Measure the Original Length of Your Material with a Micrometer.
Young’s modulus = stress/strain = (FL0)/ A (Ln − L0). This is a specific form of Hooke’s law of elasticity. The units of Young’s modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m 2). The value of Young’s modulus for aluminum is about 1.0 × 10 7 psi, or 7.0 × 10 10 N/m 2.
How to calculate Young's modulus with the modulus of elasticity formula; What Young's modulus unit is; What material has the highest Young's modulus; and more.
The definition of Young's Modulus can be expressed as: Y = s t r e s s s t r a i n = F T A Δ L L o where F T is equal to the tension force, A is equal to the cross sectional area, Δ L is equal to the change in length due to the tension force, and L o is equal to the initial length of the material.
Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc. In this article, we will discuss its concept and Young’s Modulus Formula with examples.
Young’s modulus, Shear modulus, and Bulk modulus are the three main elastic moduli used to describe the elasticity / stiffness of materials. Young’s modulus is the modulus of elasticity we use when dealing with longitudinal stress and strain.
