Understanding Young's Modulus | The Efficient Engineer
Young's modulus is an important material property in engineering: It is a measure of the stiffness of a material (i.e. a measure of how much a material will deform when acted on by a force). Metals and ceramic materials tend to have high Young's modulus values, whereas polymers have much lower values (they deform more for the …
What is Hooke's Law? (article) | Khan Academy
Young's modulus (also known as the elastic modulus) is a number that measures the resistance of a material to being elastically deformed. It is named after the 17ᵗʰ century physicist Thomas Young. The stiffer a material, the higher its Young's modulus. Young's modulus is usually given the symbol E, and is defined as:

Elastic Limit And Difference Between Elastic Limit And …
Elastic limit is the maximum stress a material can withstand before the permanent deformation. It is the material's highest limit before the material's plastic deformation can occur. Once the stress or force is removed from the material, the material comes back to its original shape. Elastomers like rubber have the highest elastic limit.
