DISLOCATION-BASED MULTI-SCALE MODELING FOR SIZE-DEPENDENT PLASTICITY OF HETEROGENEOUS MATERIALS
The objective of this research is to investigate the plastic deformation of heterogeneous material with different microstructures including grain orientations, grain size effect, and grain spatial distributions etc., and ...
Microstructural Characterization of Simulated Plastic-Bonded Explosives
Plastic-bonded explosives (PBX) are highly complex molecular composites. Recent mechanical investigations of PBX properties, in particular deformation and failure under uniaxial and cyclic loading, have revealed ...
DYNAMIC DAMAGE EVOLUTION IN ALUMINUM AS A MODEL SYSTEM FOR UNDERSTANDING FCC MATERIALS IN EXTREME CONDITIONS
Materials play a key role in many emerging technologies. Future technologies in the energy and defense sectors will place huge demands on material performance with respect to stress, strain, temperature, and pressure. These ...
