Shear modulus

OverviewExplanationShear wavesShear modulus of metalsShear relaxation modulus

The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke''s law: • Young''s modulus E describes the material''s strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),
