composite materialhammering and frequency sweep teststructural parameternatural frequencyCompared with traditional materials, composite materials have lower specific gravity, larger specific strength, larger specific modulus, and better designability structure and structural performance. However, the variability of ...
Natural frequencies of free circular plates: natural-frequency plot. This type of display may be useful in an experimental study, when the nodal patterns are obtained by holographic interferometry, or by sprinkling fine granular material on the surface of the plate, and observing the stationary ...
The radar cross section (RCS) of an infinitely long circular cylinder with a constant surface impedance is obtained via a high frequency ray solution. The ... W Nan - 《IEEE Transactions on Antennas & Propagation》 被引量: 29发表: 1982年 Analysis of natural frequencies of delaminated composite...
The graph shows that as mandible size increases so does the likelihood of predation. The curve is the fitted frequency from the GLM with dot size representing numbers (1–6) of individualG. cornutus(i.e., larger dots = more beetles). Inset shows anA. venatorabout to attack a maleG. cor...

Therefore, the paper proposes a method that would allow the estimation of scour depth for a given observed pile frequency. Introduction Scour can be defined as the excavation and removal of material from the bed and banks of streams as a result of the erosive action of flowing water [1]. ...
It is possible and common to obtain equivalent natural frequency and damping for a soil-foundation system from results of experimental or numerical analysis assuming the system has a single degree of freedom. Three approaches to extract natural frequency and damping were applied to the vertically vibr...
