Three-Dimensional Exact Free Vibration Analysis of Spherical, Cylindrical, and Flat One-Layered Panels
Table 2
Assessment 2 (part I). Simply supported aluminum cylinder with Poisson ratio and thickness ratio . Lowest exact natural circular frequencies in no-dimensional form for imposed axial half-wave number and several half-wave numbers in circumferential direction. Comparison between present three-dimensional analysis and three-dimensional analysis by Armenakas et al. [8] as adapted in Bhimaraddi [9]. is the number of fictitious layers and is the order of expansion for the exponential matrix.
