    Abstract

    In this note, we examine the zeros of a modal models of flexible structures. It is shown that in some situations the zero patterns change radically with model order. The refinement of the model by the addition of higher order modes can cause the appearance of zeros at low frequencies or in the right-half plane. Structures instrumented with piezoelectric actuators and / or fiber optic sensors are also considered.
