Fracture Modeling in Elastomeric Materials: Relating the Macroscopic Response to Microscopic Processes
DownloadFall 2018
Inelastic material behavior is known to be able to enhance the fracture toughness of elastomers. However, how to optimally exploit this toughening mechanism is still being investigated. In this thesis a series of continuum models are developed to describe such inelastic behaviors, with the goal...

Friction Stir Processing (FSP) of Thermal-sprayed Tungsten Carbide-Nickel (WC-Ni) MMC Coating
DownloadFall 2013
Tungsten carbide-Nickel (WC-Ni) metal matrix coating with fixed powder composition was deposited using low pressure cold gas dynamic spraying (LPCGDS) and High velocity oxy-fuel (HVOF) spraying. These coatings were subsequently treated with friction stir processing (FSP) as post-deposition heat...
