Vibration characteristics analysis of anisotropic metal rubber medium-thick cylindrical shells

This paper is to analyze the vibration characteristics of a metal rubber medium-thick cylindrical shell (MR-MTCS) influenced by material anisotropy. The parameters of the metal rubber (MR) are determined by the inclined helix-pyramid model (IHPM). The control equations for MR-MTCS are determined by first-order shear deformation theory (FSDT) and Rayleigh–Ritz method. The results show that the anisotropy of MR has a significant effect on the vibration characteristics of MR-MTCS. Among them, the anisotropy of Young's modulus has the most significant effect on the vibration characteristics. In addition, the effect of MR anisotropy on the vibration characteristics of MR-MTCS increases with the increase of axial half-wave number m and decreases with the increase of axial wave number n .
