High strain rate mechanical properties of
metals, ceramics and their composites. Aluminum metal foams,
aluminum hollow spheres, honeycomb structures: production and
mechanical properties. Armor materials: testing and
micro-structural analysis of penetration phenomenon, including
composite, body and foam-filled armors. Quasi-static and high
strain rate test methods, Hopkinson Pressure Bar, Drop Weight
test, Instron, projectile impact test, indentation test.
Mechanics and microstructures of polymer, metal and ceramic
matrix composites. Modeling: composite mechanics, deformation of
light-weight energy absorbing materials, wave propagation in
armor, vertical surface emitting lasers (VSEL). General research
interests: SEM, TEM, modeling, mechanical
property/microstructure relationships, stress wave propagation
in porous end dense media.
