Shear modulus G

1.1.3

The shear modulus (also sliding modulus, G-modulus, shear modulus or torsion modulus) is a material constant that provides information about the linear-elastic deformation of a component as a result of a shear force or shear stress.

G is also called the transverse shear modulus. In contrast to the elastic modulus E, which is called the longitudinal shear modulus.

Transverse shear modulus G

The material constant Poisson's ratio describes how a body deforms in the transverse direction when it deforms in the longitudinal direction. It therefore indicates the ratio of transverse strain to longitudinal strain.

The Poisson ratio is a dimensionless quantity and is symbolized by the letter ν (nu).

The Poisson's ratio is not the same for all materials and depends on the type of load and the condition of the material.
