Abstract
This paper continues the work of a previous paper by investigating the concept of an initially parabolic membrane that is "flattened" due to intrinsic stresses and then re-inflated. The pressure to obtain zero apex displacement is determined, and root mean square (RMS) error is calculated. The RMS error is then minimized by varying the pressure. We also investigate the frequency response of a support ring connected to such a membrane. It is shown that the compressive loads applied by the membrane do not change the natural frequencies of the support ring appreciably.
