Exact analysis of resonance frequency and mode shapes of isotropic and laminated composite cylindrical shells; Part II: Parametric studies

摘要

In the second part of this study, the approach developed in Part I is used to analyze parameters which effect the natural frequencies and mode shapes of circular cylindrical shells. Therefore, amplitude ratios are determined analytically for shells of different geometries. The effects of circumferential and longitudinal wave numbers and geometrical parameters are studied on longitudinal, tangential and radial motions. Finally, numerical studies are conducted to investigate the effects of composite laminate parameters on resonance frequencies. Various laminate parameters such as stacking sequence and fiber angle are considered in the study.
