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

AI Thread Summary
The discussion centers on the search for the shear modulus (G) of Nitronic 50 or XM-19 in a high-strength hot-rolled condition, specifically referencing UNS S20910 and ASTM A276-10 standards. Participants express surprise that major material standards like ASME or ASTM do not provide shear modulus data. Alternative sources such as keytometals.com and matweb.com were checked but yielded no results. The conversation shifts to the calculation of shear modulus from Young's modulus (E) and Poisson's ratio (ν), with a correction made to the formula used for this calculation. The correct formula is confirmed as G = E/(2(1 + ν)). The discussion highlights the importance of accurate formulas in material science and the collaborative effort to clarify technical details.

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" and "http://www.matweb.com"

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 $$\frac{E}{2(1+\nu)}$$

"E/G = 2.6" is burned into my brain, but that doesn't mean I never make typos!
 
thank you guys... now i remember; this formula i used in my graduation... :)
