What is it about?
The work presents a comprehensive study of uniform and non-uniform cantilever beams made of flexible coke can material with density 2700 kg/m3 and Young’s modulus 80.81GPa vibrating in water. The study analyzes the fluid loading and dissipation effect due to water on first bending mode frequency and corresponding quality factor/damping ratio for the uniform and non-uniform vibrating cantilever beam as the wet portion of the beam increases from zero length to its full length. Finally, the results are compared with the frequencies and quality factor the beams vibrating in ambient air.

Why is it important?
The study is important because it provides insights into the vibration characteristics of uniform and non-uniform cantilever beams vibrating in water, which is relevant for various engineering applications such as underwater structures, marine vehicles, and offshore platforms. The study also highlights the effect of fluid loading and dissipation on the vibration characteristics of the beams, which is important for designing and optimizing such structures.
Perspectives
The perspectives of the study include the potential for further research on the vibration characteristics of non-uniform cantilever beams in different fluids and under different loading conditions. The study also suggests the need for developing more accurate models for predicting the vibration characteristics of such beams, which can be used for designing and optimizing various engineering structures.
