Correction to ‘Cracking failure of curved hollow tree trunks’

R. Soc. Open Sci. 7, 200203 (Published Online 11 March 2020) (doi:10.1098/rsos.200203)

This correction refers to an error in equation 2.16, tER was used in place of t/R (see below). This has now been updated.

Corrected version

$$K=\frac{\sqrt{2{\sigma }_T(t/R)}}{(1-(1/2)\hspace{0.17em}(t/R))\sqrt{3E_L(1+(1/6)\hspace{0.17em}(t/R))}}$$
