... at the start of the cyclic stage, cyclic load frequency and amplitude, number of cycles and soil density on the load-strain-displacement response of the reinforcement are evaluated and discussed. Test results show that the cumulative displacements measured along the length of the geogrid during cyclic loading...

... specimens with mean densities of 12.4 and 17.1 kg/m³, under zero confining pressure. The estimated dynamic moduli values (shear modulus and modulus of elasticity) and damping ratio values are presented as functions of cyclic strain amplitude and loading frequency. The geofoam behavior for strains...
