... element and strain-controlled cyclic triaxial tests. EPS geofoam with density of 10 and 12 kg/m³ and Chamkhaleh sand with relative density of 55% were tested under confining pressures of 10 and 20 kPa. Normalized shear modulus and damping ratio curves were obtained and compared with the values...

...R. Alaie; R. Jamshidi Chenari In this study, a series of strain-controlled cyclic triaxial as well as bender element tests are carried out, so that the dynamic properties of mixtures of sand and expanded polystyrene (EPS) beads can be assessed under large and small-scale shear strains, respectively...

... isolation in seismic areas. Dynamic properties of sand-EPS bead mixtures are evaluated from resonant column and cyclic triaxial tests at small and large strains, respectively. Sand-EPS bead mixtures with varying EPS bead content, up to 2.5% by weight, have been tested at confining pressures of 50, 100...
