Numerical Investigation on Vibration Screening Using ...

2021-11-5 · This study investigates the application of a composite layer of geofoam and sand–crumb rubber infilled trench (GSFT) as a wave barrier. Rubber is a waste material and its safe disposal is a matter of concern. A numerical investigation was carried out using a two-dimensional finite element method (FEM) in ABAQUS software. A machine foundation was considered as the source of vibration
