Numerical Analysis of Free Vibration of Laminated Thin-Walled Closed-Section Shell Structures
Numerical Analysis of Free Vibration of Laminated Thin-Walled Closed-Section Shell Structures
- In Recent Developments in the Theory of Shells. Springer, Cham., p.479-492, 2019 .
The paper presents dynamic analysis of thin-walled laminated elements with two types of a closed-section: circular and rectangular. The studies are carried out using numerical tube and box shaped shell models with arbitrary laminate stacking sequences. Numerical results in a form of natural frequencies and corresponding mode shapes are obtained to investigate the effects of fiber angle change on the vibration of the structure. Moreover, the influence of boundary conditions, internal diaphragms and slenderness of a structure on natural frequencies and mode shapes of selected cases are also analyzed.
