A two-dimensional elastic membrane under tension can support transverse vibrations. 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… Web2.1. Cylindrical DRA. Cylindrical DRAs have been studied extensively in literature. Figure 2 shows the three-dimensional view (a) and the cross-sectional view (b) of a probe-fed cylindrical DRA.

So far, we have established that there is an infinite series of buckling loads and the lowest one is the critical one and called the Euler Buckling load. This raises the question of what do the larger buckling loads correspond to? These are loads that correspond to higher modes of buckling.
