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

Click For Summary
SUMMARY

The shear modulus (G) for Nitronic 50, also known as XM-19, in the hot rolled condition is not directly available in material standards such as ASME or ASTM. Users can calculate G using the corrected formula $$G = \frac{E}{2(1+\nu)}$$, where E represents Young's modulus and ν is Poisson's ratio. Values for E and ν can be found through online resources like Key to Metals and MatWeb. This discussion highlights the importance of verifying formulas and sourcing accurate material properties for isotropic materials.

PREREQUISITES
  • Understanding of shear modulus and its significance in material science
  • Familiarity with Young's modulus and Poisson's ratio
  • Knowledge of isotropic materials and their mechanical properties
  • Basic proficiency in using online material databases like Key to Metals and MatWeb
NEXT STEPS
  • Research the mechanical properties of Nitronic 50 (XM-19) from reliable material databases
  • Learn how to calculate shear modulus using Young's modulus and Poisson's ratio
  • Explore the implications of shear modulus in engineering applications
  • Investigate other high-strength alloys and their mechanical properties
USEFUL FOR

Material scientists, mechanical engineers, and anyone involved in the selection and application of high-strength alloys like Nitronic 50 or XM-19.

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... :)
