In the publication of this article (Nagaashi et al., 2018), there was an error in equations (7) and (10).

The error:
$$ {v}_{cr}\cong 3.86\frac{\gamma^{\frac{5}{6}}{\left[\left(1-{v}^2\right)/\varepsilon \right]}^{-\frac{1}{3}}}{R^{\frac{5}{6}}{\rho}^{\frac{1}{2}}}, $$
$$ {v}_{cr}\cong 35\frac{\gamma^{\frac{5}{6}}{\left[\left(1-{v}^2\right)/\varepsilon \right]}^{-\frac{1}{3}}}{R^{\frac{5}{6}}{\rho}^{\frac{1}{2}}}, $$
Should instead read:
$$ {v}_{cr}\cong 3.86\frac{\gamma^{\frac{5}{6}}}{{\left[\left(1-{v}^2\right)/\varepsilon \right]}^{-\frac{1}{3}}{R}^{\frac{5}{6}}{\rho}^{\frac{1}{2}}}, $$
$$ {v}_{cr}\cong 35\frac{\gamma^{\frac{5}{6}}}{{\left[\left(1-{v}^2\right)/\varepsilon \right]}^{-\frac{1}{3}}{R}^{\frac{5}{6}}{\rho}^{\frac{1}{2}}}, $$

This has now been updated in the original article (Nagaashi et al., 2018).
