Edge fracture of AHSS sheets under out-of-plane loading followed by in-plane loading
(Massachusetts Institute of Technology, 2015)
In recent years edge fracture has become a challenge in the manufacturing industry with the dramatical increase in the application of light-weight materials such as Advanced High Strength Steels (AHSS) and aluminum alloys. ...
Quantifying exchange processes in the urban canopy layers of dense neighborhoods
(Massachusetts Institute of Technology, 2015)
There is a global trend towards urbanization, particularly in developing regions that are home to new and rapidly growing cities. In the center of large, dense urban areas, weak exchange between the urban canopy layer (UCL) ...
Miniature, high-speed imaging transform spectrometers and advanced sampling algorithms
(Massachusetts Institute of Technology, 2015)
This thesis describes the development of miniature imaging Fourier transform spectrometers and irregular sampling techniques. An imaging spectrometer is a device that takes a series of images that include information from ...
Efficient multiscale methods for micro/nanoscale solid state heat transfer
(Massachusetts Institute of Technology, 2015)
In this thesis, we develop methods for solving the linearized Boltzmann transport equation (BTE) in the relaxation-time approximation for describing small-scale solidstate heat transfer. We first discuss a Monte Carlo (MC) ...
Studies of non-diffusive heat conduction through spatially periodic and time-harmonic thermal excitations
(Massachusetts Institute of Technology, 2015)
Studies of non-diffusive heat conduction provide insight into the fundamentals of heat transport in condensed matter. The mean free paths (MFPs) of phonons that are most important for conducting heat are well represented ...
Observation and manipulation of the wave nature of phonon thermal transport through superlattices
(Massachusetts Institute of Technology, 2015)
As the scale of electronic, photonic, and energy harvesting devices has shrunk, the importance of understanding nanoscale thermal transport has grown. In this thesis, we investigate thermal transport through superlattices ...
