# Shear Modulus (G) for Nitronic 50 or XM-19 Hot Rolled Condition

## Main Question or Discussion Point

I am looking for shear modulus (G) for Nitronic 50 or XM-19 High strength hot rolled condition

UNS - S20910 and ASTM A276-10

it is surprising for me that material standards like ASME or ASTM does not provide shear modulus data..?

even checked "http://www.keytometals.com" [Broken] and "http://www.matweb.com" [Broken]

but didnt found....

is there alterative source to find shear modulus data...

regards

For isotropic materials, $$G = \frac{E}{1 + 2 \nu}$$

A Google search soon found values for Youngs modulus $E$ and Poisson's ratio $\nu$

You are correct that the shear modulus can be calculated from Young's modulus and the Poisson ratio, but the formula you gave is incorrect.

G = E/(1+$\nu$)/2

Oops. You are right. Of course if should be $$\frac{E}{2(1+\nu)}$$
