In addition, the nonlinear behaviour of spherical pneumatics subjected to axisymmetric rigid plate and rigid cylinder loads is treated, again considering effects of wrinkling in both the load and the support zone. These results are compared with those for the concentrated load case and the differences in behaviour from a design point of view are highlighted.

Two kinds of loads, those in which the ring is attached to the membrane and a second type in which sliding of the ring relative to the membrane is permitted, are treated. A number of new features, including contact between portions of the membrane inside and outside the ring, wrinkling both within and outside the ring load, and the possibility of the load sliding relative to the membrane, are examined and their effect on the overall behaviour of the structure evaluated. The results are compared, where approriate, with those for the concentrated and rigid plate loads.
