Abstract: Adding fiber reinforcement to a loose sand alters the effective stress of the sand skeleton. The rate of pore water pressure build-up when undrained is reduced, and liquefaction may be delayed or prevented. Here the results ...

Abstract: Retaining walls are widely used for shoring excavations and stabilizing earth slopes. They often support naturally formed soils above the groundwater table and compacted soils, which are in an unsaturated state. To perform ...

Abstract: Mixing discrete flexible fibers into sand is a reinforcement technology that increases the sand’s strength as well as ability to resist liquefaction. This study demonstrates the mechanisms by which the applied loads are ...

Abstract: Rock cutting and rock penetration are typical problems in civil, mining, petroleum, and geothermal engineering disciplines. They involve dynamic fracturing and fragmentation of rock, high-speed movements of a cutter/impactor, ...
