Professor Abu Al-Rub research interests include multi-scale theoretical, computational, and experimental solid and structural mechanics, high speed impact damage, nonlocal and strain gradient theories, size effects at the micron and nano length scales, damage and fracture mechanics, cyclic plasticity, mechanics of the micro/nano structures (e.g. thin films, nanowires, electronics). He is working on development of micromechanical-based constitutive and computational models for metals and metal alloys, fiber reinforced composites, concrete, ceramics, and polymers.
