Abstract: Many poorly graded granular materials of engineering importance can be characterized as gap-graded binary mixtures. Such mixtures display a volume-change response at a threshold value of the coarse fraction that is reminiscent ...

Abstract: This paper describes the current work on a large deformation soil model to demonstrate the feasibility of particle models to simulate full-scale vehicle-soil interaction problems in which the soil undergoes large excavation-like ...

Abstract: Subgrade rutting failures in matting structures present a unique challenge in expedient airfields. Mats are often constructed over existing soft subgrades and can experience aircraft with large gross loads and high tire ...
