Examples of Modulus of Rigidity

Here are some examples of modulus of rigidity for various materials:

Material

Modulus of Rigidity Value

Concrete

3 x 106 psi (21 GPa)

Wood

13 GPa

Brass

40 GPa

Rubber

0.0003 GPa

Ideal liquid

0 GPa

Modulus of Rigidity of Steel

Modulus of rigidity for steel is approximately 79 GPa (Gigapascals) or 79,000 MPa (Megapascals). This value represents the material’s resistance to shearing or torsion forces.

Modulus of Rigidity of Aluminum

Modulus of rigidity for Aluminum can vary slightly with different alloys and other factors, but typical values for the modulus of rigidity of aluminum materials used in the industry range from 24 to 28 GPa (Gigapascals), or 3.5 × 106 to 4.1 × 106 psi.

For example, the modulus of rigidity for aluminum 6061-T6 is approximately 24 GPa. This value represents the material’s resistance to shearing or torsion forces and is an important property for understanding the material’s behavior under shear stress.

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.

What is the Modulus of Rigidity (Shear Modulus)

Modulus of rigidity, also known as shear modulus, is a measure of the elastic shear stiffness of a material. It is defined as the ratio of shear stress to the shear strain. It can be used to explain why a material resists transverse deformations. A way to measure the mechanical properties of solids is to use the shear modulus of elasticity. The SI unit for the Modulus of rigidity is Pascal (Pa) or N/m². It is denoted by G, S, or μ...
