Mechanical Behavior of Granular/Particulate Media Reinforced with Fibers
Fiber-reinforced ganular composites (for instance, fiber-reinforced sand) are considered as construction materials for such applications as subgrades of airfields and roads, aircraft parking facilities, etc. An investigation into the mechanical behavior of granular/particulate media with fibrous inclusions was carried out. This investigation was built on the results of a previous study. Fiber-reinforced granular material was considered as a composite, and a mathematical homogenization scheme was used to arrive at its macroscopic properties. The issues related to micromechanics behavior, leading to anisotropy and hardening/softening at the macroscopic level of description, were at the core of this investigation. This research produced a material model which accurately describes the behavior of fiber-reinforced soils at failure. The research was terminated before its conclusion, because of the elimination of the Particulate Mechanics program at the AFOSR.
