Results on the large deflection and stability behavior of spherical inflatables subjected to axisymmetric hydrostatic loading are presented. Using an Eulerian description and assuming inextensibility, a set of integro-differential equations of the Volterra type defining the problem are solved numerically in the pond region. Using a numerical algorithm, the complete load-deflection behavior is determined for structures of different initial geometries and for various densities. Special attention is paid to γ = 9.0.
