Shear Modulus is a measure of strength of the shape of a body. A rigid body's shearing modules is going to be infinite and it means its shape is very consistent and to change it we need infinite force.
The ratio of shearing stress to the corresponding shearing strain is called the shear modulus of the material and is represented by G. It is also called the modulus of rigidity.
Generally to test the strength of the shape of the body its lower surface is fixed and force is applied horizontal to the upper surface.Shearing stress is the horizontal force applied per unit surface area.Shearing strain can be measured as the angle shifted by the upper surface when compared with the lower surface.
The ratio of shearing stress and strain is called shearing modulus.
