Liquefaction of Silty Sands

Feb. 18, 2019

Utilizing experience with silty-sand gained during her PhD, April intends to focus on how to use silty-sands in the centrifuge to produce accountable results to predict the influence of this material on liquefaction; hopefully leading to incorporation into performance-based design.

Physical Modeling of Buried Explosion in Soils

Oct. 18, 2017

Buried explosion is a complex phenomenon, involving high strain-rate soil dynamics, fluid dynamics, fractures, shocks and multi-scale physics. A comprehensive experimental program using geotechnical centrifuge modeling was conducted in conjunction with computational modeling using finite element, boundary element and discrete element and meshless methods to achieve a new level of scientific understanding of the complex multi-phase phenomena.
