| | My current research interests concern mechanics of materials and constitutive modelings of advanced engineering materials. In particular, I am interested in micromechanical damage mechanics of brittle composites, micromechanics of random heterogeneous elastic and inelastic fibrous and particulate composites, continuum elastoplastic damage mechanics, plasticity and viscoplasticity theories and computational algorithms, advanced constitutive modeling of materials, nonlinear computational mechanics, nondestrucdtive and destructive testing, durability, reliability, sulfate attack, and construction defects. Applications can be made to plain and rebar/cable reinforced concrete, fiber reinforced concrete, cementitious composites, mortar and stucco, geological materials, advanced ceramics and ceramic composites, polymer composites, laminated composites, multi-layered materials, metals and metal matrix composites, nanomaterials, nanocomposites, biomaterials, human bones, and so on.
In the treatment of micromechanical damage mechanics, I consider microcrack densities, orientations, sizes, locations, configurations, statistical aspects, interactions, fracture mechanics criteria, and evolutionary microcrack models. The effects of microcracks and their interactions on effective properties of brittle solids are investigated. Similarly, the microgeometry and interaction effects of fibers and particles in heterogeneous composites on overall effective properties of elastic and inelastic composites are studied. Rigorous local micromechanical solutions together with the volume/ensemble averaging procedures lead to innovative predictions of mechanical properties of composites. Materials science imaging is used to characterize microstructures.
I also perform studies in nondestructive and destrucitve testing of concrete and stucco subject to sulfate and environmental attack; damage, fracture and failure of concrete components and systems; and construction defects (construction defect expert).
The continuum elastoplastic damage mechanics research involves the development of rigorous operator splitting methodology, constitutive integration equations, return mapping algorithms, parameter estimation, experiemental validations, and consistent tange nt operators for the finite element implementation. In computational mechanics, my research involves solution strategy for finite element methods, nonlinear frictional contact problems, strain softening damage and plasticity, and localization of deformation problems. |
