Characterization and numerical simulation of the microstructural and micromechanical viscoelastic behavior of oil sands using the discrete element method
… shovel-formation interactions, and coupled deformation-stress under dynamic loading. A 2-D DEM model of the oil sands is built and simulated in PFC2D. The simulation results show that the generalized Burgers model with five Kelvin-Voigt elements fully characterized the microscopic …

Continuum modeling of electro-chemo-mechanical phenomena in all-solid-state batteries
… captures the continuous evolution of mechanical stresses, interfacial damage, and non-uniform current distribution across particles in a microstructure. We specialize on an LCO-LGPS composite cathode and study the evolution of interfacial damage under varying material and microstructural …

Modeling volcanic unrest by data assimilation
… mechanisms involved in volcanic unrest, such as deformation, failure, and pore fluid migration. First, using a series of tests based on the synthetic data, I optimize a data assimilation technique, Ensemble Kalman Filter (EnKF), to improve its performance in forecasting volcanic unrests with …

The Effect of Plastic Deformation on a Series of Thin Magnetic Films
… degrees of lateral strain to induce plastic deformation in the thin magnetic film by (1) bending over a cylinder of fixed radius and (2) straining the sample laterally using an Instron 5566 materials tester. The magnetic properties were measured after each straining session via VSM using a …
