Understanding Modulus of Rigidity in Physics | Physics Girl

It''s worth noting the relationship between modulus of rigidity (G) and Young''s modulus (E). While Young''s modulus quantifies a material''s resistance to axial or tensile stress, the modulus of rigidity measures its resistance to shear stress. These two moduli are related by the equation: E = 2G (1+ν) Where: E = Young''s Modulus

Young''s modulus and Poisson''s ratio From the truss and strain laboratories you are now familiar with at least two elastic constants. If we apply a uniaxial tensile stress sL to a constant cross-section rod of material, we will obtain a biaxial state of strain, consisting of an axial tensile strain eL and a transverse strain eT .The axial strain will be tensile for a tensile applied stress

elasticity

$begingroup$ it may very well be that this is your answer, but be aware that shear modulus is not the same thing as tensile or Young''s modulus. I''ve seen the equation you wrote above which has shear modulus in it, but I''ve not seen it for E, which is Young''s modulus. I''m just saying it is probably worth your time to continue to look into this.

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),

Relation Between Elastic Constants

Young''s modulus, bulk modulus and Rigidity modulus of an elastic solid are together called Elastic constants.
