Investigation of Failure Modes of Fiber Reinforced Polymer Composite Flywheel Rotors for Energy Storage Systems
DownloadFall 2022
High-velocity and long-lifetime operating conditions of modern high-speed energy storage flywheel rotors may create the necessary conditions for failure modes not included in current quasi-static failure analyses. The central hypothesis for this thesis research is that (i) viscoelastic effects...

On the Mechanical Properties and Failure of Low-Pressure Cold-Sprayed Tungsten Carbide-Nickel Metal Matrix Composite Coatings
DownloadFall 2019
Tungsten carbide-Nickel (WC-Ni) metal matrix coatings (MMC) were fabricated using a low-pressure cold spray unit. The coatings were designed according to 50, 71, and 92 weight percentages of WC in the feedstock powder. These coatings were subsequently prepared for uni-axial quasi-static tensile...
