Research Interests
Dr. Dai’s primary research area is computer modeling and
analysis of multi-phase heterogeneous composites such as infrastructure
materials, based on the image processing of composite specimens.
Numerically and experimentally investigates the link between
microstructure and macro mechanical properties, damage/fracture
mechanisms, and nonlinear constitutive behaviors of heterogeneous
composites. Additional research interests include micromechanics,
nanostructured materials, biomechanics, computer-aided design,
pavement technology, and infrastructure engineering.
