Click For Summary
SUMMARY

The discussion centers on calculating Poisson's ratio using Young's modulus and Bulk modulus. A specific formula, (3*K-E) / 6K, is highlighted as the method to derive Poisson's ratio when given the values of Young's modulus (E) and Bulk modulus (K). The reference to the Wikipedia page on Poisson's ratio provides essential conversion formulas that aid in understanding the relationships between these material properties. Participants emphasize the importance of these formulas for accurate calculations in material science.

PREREQUISITES
  • Understanding of Young's modulus (E)
  • Familiarity with Bulk modulus (K)
  • Knowledge of Poisson's ratio (ν)
  • Basic mathematical skills for applying formulas
NEXT STEPS
  • Study the derivation of the formula for Poisson's ratio from Young's and Bulk moduli
  • Explore additional material properties and their interrelations
  • Learn about the applications of Poisson's ratio in engineering and material science
  • Review the table of conversion formulas on the Wikipedia page for Poisson's ratio
USEFUL FOR

Students and professionals in engineering, material science, and physics who need to understand the relationships between Young's modulus, Bulk modulus, and Poisson's ratio for practical applications and calculations.

Homework Statement
Given that the sample of PVC has a Young's modulus of 3.3GPa and a Bulk modulus of 4.6GPa Calculate Poisson's ratio
Relevant Equations
None
I've never really heard of Young, Bulk, or Poisson's ratio before. I have done some research but I can't seem to find the relationship between the three in order to calculate Poisson's ratio. Could someone please point me in the right direction?

Thanks

Hi,

Yes I have individually researched Bulk, Young, and Poisson's ratio, but from what I've researched I am not sure how to apply it all to calculate Poisson's ratio with the information I have been given in the question.
 
Well, there is a formula in that reference that will enable you to calculate PR given Young's and Bulk moduli. As to "understanding how to apply it all", I couldn't tell you off the top of my head how that formula is derived, but there it is and you can use it.
 
Hi Chester,

Thank you I didn't see this table, the following formula provided me with the correct answer:

(3*K-E) / 6K
