What is Modulus of Elasticity
Modulus of Elasticity, or Young Modulus of Elasticity or Elastic Modulus, is a fundamental mechanical property of materials that measures their stiffness or resistance to elastic deformation under stress. It is also defined as the ratio of tensile stress (σ) to tensile strain (ε), where
Stress is the amount of force applied per unit area (σ = F/A) and strain is extension per unit length (ε = dl/l).
- Modulus of Elasticity was introduced by a famous British polymath and physician Sir Thomas Young who was born on 13th June, 1773. He was well known for the discovery of many theories and experiments such as – Young’s modulus, Young’s interference experiment, Astigmatism, Young-Helmholtz theory and Young Temperament.
- This property is essential in engineering and materials science, as it determine a material’s ability to support loads and maintain its shape.
- One of the most important tests in engineering is knowing when an object or material will bend or break, and the property that tells us this is the Young’s modulus. It is the measure of how easily a material stretches and deforms.
- Modulus of Elasticity is also known as Young Modulus, tensile modulus and elastic modulus.
- Whether it is a small piece of rubber or large piece, its modulus of elasticity will always be same.
Modulus of Elasticity Definition
Modulus of Elasticity is the material’s resistance to the deformation force. It is the ratio of stress acting on the body to the strain produced.
Modulus of Elasticity
Modulus of Elasticity or Elastic Modulus is the measurement of resistance offered by a material against the deformation force acting on it. Modulus of Elasticity is also called Young’s Modulus. It is given as the ratio of Stress to Strain. The unit of elastic modulus is megapascal or gigapascal
Modulus of Elasticity is one of the most important concepts of material science and engineering. It is the property of material that measures stiffness to elastic deformation under stress. In this article, we will discuss about Modulus of Elasticity, including its definition, types, and fundamental concepts along with its various applications in day-to-day life.
