Comparison to Laplace estimates. a Geometric setup with R the inner radius and T the thickness of the spheres. A pressure $p_{\mathrm{infl}}$ was applied to the inner surface ${\mathrm{\Gamma }}_{\mathrm{endo}}$. b Dirichlet boundary conditions were enforced at the intersections of the Cartesian axes with the outer surface ${\mathrm{\Gamma }}_{\mathrm{epi}}$. Displacements at these points were restricted to be along the respective intersecting axes. c Transversely isotropic setup with one fiber family in the circumferential direction
