We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts. Young's modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. Elastic modulus is a key parameter employed to estimate the deformation of structures and structural members and is typically expressed in terms of the compressive strength [, , , ]. where E is known as the elastic modulus or Young's modulus. The increase and decrease of elasticity depend upon the type of … An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it.

An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments - Volume 7 Issue 6. Although the general proportionality constant between stress and strain in three dimensions is a 4th-order tensor called stiffness , systems that exhibit symmetry , such as a one-dimensional rod, can often be reduced to applications of Hooke's law. Your story matters Citation Li, Han, and Joost J. Vlassak. Modulus of Elasticity - is a measure of stiffness of an elastic material.
