- Summary:
- A continuous system approach to the vibration characteristics of a symmetrically slotted beam has been developed. The beam was modelled as a Bernoulli-Euler beam with a reasonable stress distribution associated with the slots. The equation of motion was developd and resonant frequencies obtained from Rayleigh's Quotient. An experimental study of an aluminum beam with symmetrical slots was performed. The resonant frequency and apparent mass (a measure of damping) were measured. Reasonably good correlation in natural frequencies between theory and experiment was obtained. The reduction in natural frequency was a more sensitive indicator of damage than was the increase in damping. 7 refs., 7 figs.
