The SI unit of shear modulus is the Pascal (Pa), but values are usually expressed in gigapascals (GPa). It can be used to explain how a material resists transverse deformations but this is practical for small deformations only, following which they are able to return to the original state. There are a number of different types of strains to consider when choosing your materials and application.

The shear modulus is a measure of the ability of a material to resist transverse deformations and is a valid index of elastic behaviour only for small deformations, after which the material is able to return to its original configuration. 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. Ans: The shear modulus is related to other elastic moduli as 2G(1+υ) = E = 3K(1−2υ). As stresses are increased or decreased a material body will tend to change size and shape as strains occur: stiffness is the relationship between changes of stress and changes of strain. poisonous atmosphere?
