What is transverse elastic modulus?
When a shear force acts on an object, a shear stress τ is generated and a shear strain γ occurs.
In addition, the deformation due to the shear stress τ does not involve a change in length, but rather a change in angle.
Within the elastic limit of the material, the shear stress τ and the shear strain γ are proportional to each other.
This proportionality constant is called the transverse elastic modulus or shear elastic modulus and is expressed as G.
G=τ/γ
In an isotropic elastic body, if the longitudinal elastic modulus E and Poisson's ratio ν are known, then G can be calculated as follows:
It can be calculated using the following formula.
G = E/2 (1 + ν)
