About Ruqiang Feng
Dr. Feng's research is focused on experimental and computational mechanics of materials. Areas of interest include inelastic deformation, damage and failure mechanisms of solids, high strain rate and shock wave phenomena, rheology of polymers and polymer compounds, surface mechanics and tribology (friction and wear), polycrystal modeling and simulations, and hybrid atomistic-continuum modeling and simulations of defects/heterogeneities in materials and material systems. Some of the recent research projects are:
- The Role of Fracture Surface Topography and Friction in Dynamic Response of Armor Ceramics (DEPSCoR/ARO project): A novel experimental approach that combines Kolsky-torsion-bar tribometric experiment with 3-D non-contact surface profilometry is developed and used to characterize the dynamic tribological response of fractured material surface pairs.
- Polycrystal Modeling of Ceramics Subjected to High Strain Rates and Pressures (DEPSCoR/ARO project): A material modeling technique that combines Voronoi-polycrystal microstructural model with FE analysis is developed and employed to analyze intragranular microplasticity and intergranular microdamage in polycrystalline ceramics subjected to impulsive compression and tension.
- Multiscale Treatment of Solid-Fluid Interfaces: Development of Hybrid Monte Carlo and Finite Element Code (NFS ITR project): A coarse-grained Monte Carlo (CGMC) method and a hybrid atomistic-quasicontinuum modeling technique using CGMC for length scale coupling are developed and applied for modeling and simulation of a tribological system involving thin-film lubrication.
- Manufacturing of Novel Continuous Nanocrystalline Ceramic Nanofibers with Superior Mechanical Properties (NSF NIRT project): A Voronoi-polycrystal-based FE model for nanocrystalline materials is developed and used to study the nanomechanical behavior of nanocrystalline ZrO2 nanofibers.
