TL;DR: In this paper, a simplified super-element method was used to analyze the properties of a periodically stiffened-thin-plate filled with viscoelastic damping material (VDM), which can be used in designing a periodic or quasi-periodic thin plate and shell structures for improving the mechanical property.
Abstract: Flexural vibration characteristics of a periodically stiffened-thin-plate filled with viscoelastic damping material (VDM) are researched originally based on a simplified-super-element-method (SSEM) according to Floquet–Bloch׳s theorem and super-element-method (SEM). The density, damping ratio (the parameters of the VDM), and the lattice constant of the structure, which impact the frequency characteristics of periodically stiffened-thin-plate, are thoroughly analyzed. The SSEM developed in this research ensured the accuracy and simplified calculation work. It can be used in designing a periodic or quasi-periodic thin plate and shell structures for improving the mechanical property. The advantages of this method are verified by comparing the structures that is and is not filled with VDM.
