Ph.D. in Mechanical Engineering
Overview
Ph.D. students normally develop individual programs of study in mechanical systems/design, fluid mechanics, solid mechanics or thermal science. In addition, there are also opportunities for interdisciplinary programs such as biomechanics, geomechanics, manufacturing, material science, ocean engineering, and micro/nano sciences.
Areas of Concentration
Mechanical Systems/Design
This area encompasses the broad field of computer-aided design including design methodology and computer graphics, as well as kinematics and dynamics of machines, vibrations, design of machine elements, controls, automation, and techniques for assessing reliability. Current areas of research include non-linear dynamics & vibrations, vibration-based structural health monitoring and failure prediction, expert systems, machine tool calibration, control of robot vehicles, kinematic design and optimization, computer-aided design of control systems, precision machining, surface roughness analysis, and robot-assisted waterjet machining.
Fluid Mechanics
The fluid mechanics program includes advanced studies in laminar and turbulent flows, computational fluid dynamics, experimental methods, flows in micro-domains, flows with particulate matter, biological flow. Current areas of research include fluid flow and heat transfer in micro-domains, flow in human airways, computational fluid dynamics in irregular geometries, biological flows, and numerical direct simulation flow modeling.
Solid Mechanics
Studies in solid mechanics involve strength of materials, elasticity, plasticity, continuum mechanics, composite materials, fracture and fatigue, vibrations, wave propagation, computational methods, and micromechanics. Applications of these studies are applied to the mechanical and thermomechanical behavior of metals, composites, functionally graded materials, ceramics, and geological media under both static and dynamic loading conditions. A significant portion of our studies has been involved with micromechanical material behavior. Areas of current research include: behavior of materials under shock loading, dynamic fracture mechanics and material behavior, finite element modeling of biological materials, computational simulation of particulate composites, cellular and granular materials, fatigue crack growth, micromechanical behavior of composites.
Thermal Sciences
The area of thermal science includes studies of thermodynamics, conduction, convection and radiation heat transfer, pollution, and energy processes. Recent research has been involved with experimental and numerical modeling of cooling of circuit boards, heat transfer and fluid flow in melting and solidification, micro heat transfer, aerosol transport in human respiratory flows, direct control heat transfer with phase change, computation of natural and forced convection in complex enclosures, energy system analysis including heating, ventilating, air conditioning, refrigeration, and electrical power systems.
