DYNAMIC RESPONSE OF SAND REINFORCED WITH RANDOMLY DISTRIBUTED FIBERS

A description is given of discrete, randomly distributed, fiber-reinforced sand (RDFS) under dynamic loads. The influence of selected fiber parameters and test variables (i.e. shearing-strain amplitude, confinining stress, cyclic prestraining, number of cycles) and fiber properties (i.e. content orientation, aspect ratio) on the dynamic modulus and damping response is considered. It was found that the inclusion of fibers has a significant influence on the dynamic response of sand, namely, shear modulus, and damping ratio. This influence is primarily a function of certain parameters (cyclic shearing strain amplitude and confining stress) and fiber properties (content, orientation, aspect ratio, and modulus). The conclusions drawn from the study are presented.
