WebJan 6, 2016 · Circular cylindrical shells are widely used in engineering structures, such as rockets, aircrafts, submarines, and pipelines. Due to the extensive application, the vibration characteristics of circular cylindrical shells have been a … WebThe resonant mode is the localization of the energy density in the cylindrical cavity. The total energy density corresponding to each resonant mode is the contribution of the electric field and the magnetic field prevailing in the cylindrical cavity. Once a cavity is in resonance, it remains in that mode without any input energy.

The properties of an idealized drumhead can be modeled by the vibrations of a circular membrane of uniform thickness, attached to a rigid frame. Due to the phenomenon of resonance, at certain vibration frequencies, its resonant frequencies, the membrane can store vibrational energy, the surface moving in a characteristic pattern of standing waves. This is called a normal mode. A me…
