摘要: In this chapter, we will consider two-dimensional, continuous vibrating systems, with and without stiffness. An ideal membrane, like an string, has no stiffness of its own, thus, oscillations depend upon the restoring force supplied by externally applied tension. A plate, on other hand, a bar, can vibrate fixed or free ends external
