Elastic modulus - Wikipedia
网页An elastic modulus (also known as modulus of elasticity) is the unit of measurement of an object's or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it.

12.4: Stress, Strain, and Elastic Modulus (Part 1)
网页2023年6月14日 · The elastic modulus for tensile stress is called Young’s modulus; that for the bulk stress is called the bulk modulus; and that for shear stress is called the shear modulus. Note that the relation between stress and strain is an observed relation, measured in the laboratory.
Elastic Moduli - an overview | ScienceDirect Topics
网页Elastic moduli measure the stress required to elastically deform the material to a predefined strain. Either of two interdependent pairs of elastic moduli fully describes the elastic behavior of isotropic homogeneous materials.

Elasticity and Young’s Modulus (Theory, Examples, and Table of …
网页2020年8月5日 · Young’s modulus–the most common type of elastic modulus, seems to be the most important material property for mechanical engineers. It’s pretty important for materials scientists, too, so in this article I’m going to explain what elasticity means, how to calculate Young’s modulus, and why stiffness is so important.
