Fig. 4. The small-stress asymptotic prediction of eqn (12) (lines) accurately capture the finite-element simulation results (symbols) even for intermediate stress values. Here ν = 0.1 and rout/rin = 2 in the geometry of Fig. 1. (a and b) A fiber-like bucklable model, (c and d) a very anti-bucklable model mimicking a granular medium, (e and f) a neo-Hookean model. The values of 
pictured in (b and c) are marked by dashed arrows in Fig. 3, and background shading follows the same convention. The estimated magnitude of the error induced by the finiteness of the simulation mesh size is comparable to the symbol size.
