Questions and Answers

What is the formula for Young's modulus Y in terms of interionic separation r?

$Y = 7.54 \times 10^{10}$

$Y = \frac{1}{6r} \frac{d}{dr} \left( r^2 \frac{dE(r)}{dr} \right)$ (correct)

$Y = 8.364 \times 10^{-95} r - 1.3433 \times 10^{-28} r^4$

$Y = \frac{1}{8.06 \times 10^{28} r^3 + 501.84 \times 10^{96} r^{10}}$

What does the bulk modulus K represent in the given context?

Relationship between Young's modulus and interionic separation

Poisson's ratio

Response of a material to hydrostatic pressure (correct)

Interionic separation

Based on the Peierls-Nabarro model, how are the elastic modulus Y and bulk modulus K related?

$K = Y/3(1-2\nu)$ (correct)

$K = Y(1-2\nu)/3$

$Y = K/3(1-2\nu)$

$Y = K(1-2\nu)/3$
