...Huiyu Li; Hua Li; Hornsen Tzou Fig. 3 The cross section of an LaSMP laminated cylindrical shell Through changing the patch length from L /5 to 4 L /5, the 1st natural frequency can be adjusted from 27.4 Hz to 31 Hz and the frequency variation percentage achieves 13% (Fig. 11...

... of circular cylindrical shells made of functionally graded (FG) materials. The development is based on a combination of linear Sanders thin shell theory and the classic finite element method. Material properties are temperature dependent and graded in the shell thickness direction according to a simple power...

...Zhiyuan Cao; Shougao Tang Upon the basic theory of functionally graded material cylindrical shell, the original 3-D foundational equations with variable coefficients are transformed into anisotropic and membrane-bending coupling 2-D equations with constant coefficients. The separation-of-variables...

...Tian Ran Lin; Chris Mechefske; Peter O’Shea Characteristics of modal sound radiation of finite cylindrical shells are studied using finite element and boundary element methods in this paper. In the low frequency range, modal radiation efficiencies of finite cylindrical shells are found...
