Elastic Modulus

Elastic modulus, also known as Young's modulus, measures a material's stiffness. It quantifies how much a material resists deformation when a force is applied. A high elastic modulus means the material is stiff and doesn’t stretch or compress much under load, like steel. A low elastic modulus indicates the material is more flexible, like rubber. It is calculated by dividing stress (force per area) by strain (the resulting deformation). Essentially, elastic modulus helps us understand how a material will behave under mechanical stress, indicating its ability to return to its original shape after being deformed.
