We derive in the scope of large deflection the curvatures of free-standing, circular glassy splay-bend and twist nematic sheets responding to light and heat. In comparison with the existing results for small deformations, the solution of the splay-bend nematic sheet is of identical form, but the solution of the twist nematic sheet exhibits significantly different features including size dependence and bifurcation.
