RESEARCH INTERESTS

• Computational Modeling and Mechanics:  hierarchical models spanning the nano to the macro scales; prediction of material and structural response based on physically based material models
  
  
• Failure models for heterogeneous ductile and brittle systems: fracture mechanics; plasticity; microstructural effects due to grain-boundaries, cell walls, sub-grains and grain morphology
  
  
• Dynamic behavior of structures and materials: stress waves in solids; structural dynamics; mechanical behavior of composite structures subjected to high impact velocities; grain-boundary and interfacial effects
  
  
• Experimental Solid Mechanics: AFM, TEM, and SEM quantitative measurements of nano and micro failure surfaces; universal scaling laws, dynamic failure
  
  
• Micromechanics: strengthening and toughening mechanisms in composites; mechanical behavior and structural integrity; mechanical response of ceramics, intermetallics, and polymers; interfacial fracture mechanics
