What is the relation between Young’s Modulus (E), Bulk Modulus (K), and Poisson’s Ratio (nu)?
AE = 3K (1 - 2 nu)
BE = 2K (1 + nu)
CE = 9K / (1 + 2 nu)
DE = 3K (1 + 2 nu)
Explanation
The fundamental elastic constants relate as: E = 3K(1 – 2*nu) and E = 2G(1 + nu). Combining them gives E = 9KG / (3K + G).
