On the effects of using nonlinear springs in mono-coupled periodic structures

Abstract Many strategies are employed to control structural vibration. One of them is to design structural elements in a periodic arrangement to obtain the so-called bandgap effect. For infinite periodic structures, bandgaps are defined as frequency ranges where waves do not prop...

Time-domain analysis of fractional-order viscoelastic sandwich plates via shifted Legendre polynomial approach

The objective of this study is to investigate the dynamic characteristics of three-dimensional fractional-order viscoelastic sandwich plates. Based on the fractional Kelvin–Voigt constitutive relation, the governing equations involving the spatial variables $(x,y,z)$ and the temp...
