Relation Between Modulus of Rigidity and Modulus of Elasticity
The relationship between Modulus of Rigidity(G) and Modulus of Elasticity(E) is given by the formula,
E = 2G(1 + v)
where,
- G is the Shear Modulus
- E is the Modulus of Elasticity
- v is the Poisson’s Ratio
Note:
(Elastic Constant)E = 9KG/(3K+G)
Modulus of Rigidity
Modulus of rigidity also known as shear modulus, is used to measure the rigidity of a given body. It is the ratio of shear stress to shear strain and is denoted by G or sometimes by S or μ. The modulus of rigidity of a material is directly proportional to its elastic modulus which depends on the material’s nature and properties.
In this article, we will talk about what Modulus of rigidity is, its formula, examples, and applications.
