Help with Shear Modulus Research

[RCulling]

I was wondering if anyone could please point me in the direction of some background info on who (and why) someone defined the equations definition of the shear modulus, I've searched in google and wiki and havnt found anything useful. Just a link or something would be great

It is similarly defined as the modulus of elasticity

Modulus of Rigidity = Shear force/ Shear strain

It is also related to the modulus of elasticity E by

$$G=\frac{E}{2(1+\nu)}$$ where v is the Poisson's ratio.

thanks :) but I was more wanting the person that defined it, I've to write a report on it, and need some background info... Which I can't seem to find

 

[rock.freak667]

In that case, I do not know as well. Sorry.
