Modal analysis of thin cylindrical shells with cardboard liners and estimation of loss factors
Cardboard liners are often installed within automotive drive shafts to reduce radiated noise over a certain frequency range. However, the precise mechanisms that yield noise attenuation are not well understood. To overcome this void, a thin shell (under free boundaries) with different cardboard liner thicknesses is examined using analytical, computational and experimental methods. First, an exp...
متن کاملStatic and modal analysis of parabolic-boundary functionalized Carbon nanotube-reinforced composite plates using FEM
This paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. Five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. For each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...
متن کاملStability analysis of dynamic thin shells
We analyze the stability of generic spherically symmetric thin shells to linearized perturbations around static solutions. We include the momentum flux term in the conservation identity, deduced from the “ADM” constraint and the Lanczos equations. Following the Ishak-Lake analysis, we deduce a master equation which dictates the stable equilibrium configurations. Considering the transparency con...

متن کاملVibration Analysis of Thin Cylindrical Shells Using Wave Propagation Approach
The vibration analysis of cylindrical shells using wave propagation method is presented. Results obtained using the method have been evaluated against those available in the literature. Comparison of the results by the present method and numerical "nite element method is also carried out. It is possible to conclude through the comparisons that the present method is convenient, e!ective and accu...
