Research in Computational Mechanics in the department of Civil Engineering and Engineering Mechanics is led by Professors Fish, Waisman, Giometto and Sun and involves a wide range of topics, for example: Advanced discretization techniques for modeling fracture phenomena of natural or man-made solids subject to a range of loading conditions, e.g. damage and phase field methods, extended finite element methods, and cohesive zone methods. Multiscale and multigrid methods in space and time, e.g. homogenization and concurrent approaches, coupling of atomistic/discrete/continuum systems, dimensional-reduction methods with applications to composite materials, energetic materials, concrete, metals, printed materials and geomaterials such as soil, rock and ice. Solver techniques and analysis of multi-physics problems, e.g. hydraulic and chemo-driven fracture, crystallization induced damage, impact and blast problems, and fluid-structure interaction. Development and validation of turbulence closure models (large-eddy simulation, Reynolds-averaged Navier-Stokes), and design of reduced-order formulations for boundary-layer and canopy flows. Verification and validation, e.g. numerical analysis, optimization, error estimation and error analysis, inverse problems that leverage data from micro-CT images, digital image correlation and other advanced experimental techniques. Stability and material bifurcation of path-dependent solids, e.g. shear banding, brittle and ductile fracture and cataclastic flow. Software development, high-performance computing and adaptive methods.
