We study the problem of changing the geometric configuration of an elastic plate by means of attached and embedded actuators. For this purpose we use the so-called "full" von Karman plate equations, incorporating geometric nonlinearities, and we develop a model for internal actuation based on the same principles and assumptions. We show that the von Karman model predicts azimuthal buckling for a thin, centrally supported disk-shaped plate with uniform transverse boundary loading and we indicate that behavior of this type poses a significant problem in attempting reformation of the elastic plate into a rotationally symmetric, bowlshaped shell, a problem of some importance in projected applications. We study two different systems of actuator deployment and indicate why one of them appears to deal with this problem more effectively than the other.
