The material will undergo an angular deformation, and the ratio of the tangential force per unit area to the resulting angular deformation is called the shear modulus or the rigidity modulus. A shear modulus is applicable for the small deformation of the material by applying less shearing force which is capable to return to its original state. to 77% and 111% for the compression elastic modulus of the isotropic and anisotropic MREs, respectively, when SF was increased from 0.375 to 0.75. Examples of the use of shear modulus are in the design of rotating shafts and helical compression springs. When a shear force is applied on a body which results in its lateral deformation, the elastic coefficient is called the shear modulus of elasticity.

Shear stress is different from tension or compres-sion stress in that it tends to make one side of a member slip past the other side of a member adjacent to it. The shear modulus is the elastic modulus we use for the deformation which takes place when a force is applied parallel to one face of the object while the opposite face is held fixed by another equal force. Mathematically the shear modulus is equal to the quotient of the shear stress divided by the shear strain. A number in parentheses indicates the year of last reapproval.
