Modulus of Elasticity vs Modulus of Rigidity

Modulus of Elasticity of Different Materials

Modulus of Elasticity and Modulus Rigidity are two component that acts when the deforming force acts parallel and tangential respectively.

Difference Between Modulus of Elasticity and Modulus of Rigidity
Modulus of Elasticity	Modulus of Rigidity
Calculate the deformations of an object when the deforming force is applied parallel to the surface.	Calculate the deformation of an object when the deforming force is tangential to the surface.
Denoted by E	denoted by G
E = Stress/Strain	G = Shear Stress/Shear Strain
stretching or compressing type of deformation	sliding or twisting type of deformation
E = 3K(1 – 2v)	G = E/(2 + 2v)

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.
