Application of Metastructures for Targeted Low-Frequency Vibration Suppression in Plates
Ghachi, Ratiba F.; Mohamed, Ahmed S.; Renno, Jamil; Alnahhal, Wael ( Springer , 2022 , Article)Purpose We present an approach that combines finite element analysis and genetic algorithms to find the optimal configuration of local resonators created in the host structure to suppress their vibration in a target ... -

Generalized spatial aliasing solution for the dispersion analysis of infinitely periodic multilayered composites using the finite element method
Haque, A. B.M.Tahidul; Ghachi, Ratiba F.; Alnahhal, Wael I.; Aref, Amjad; Shim, Jongmin ( American Society of Mechanical Engineers , 2017 , Article)The finite element (FE) method offers an efficient framework to investigate the evolution of phononic crystals which possess materials or geometric nonlinearity subject to external loading. Despite its superior efficiency, ...
