Flaw identification from forced vibration testing
Description:
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 c…
