A study on the effect of print parameters on mechanical properties of parts manufactured using additive manufacturing
DownloadFall 2017
This thesis presents an investigation on material-process interaction of vat-photopolymerization processes. The effect of different printing factors on tensile properties is studied. Two vat-photopolymerization processes are considered: Digital Light Processing (DLP) and Stereolithography (SLA)....

Application of Thermally-Sprayed Coatings as Heat Tracers for Carbon Steel Pipes to Mitigate the Effect of Ice Accumulation and Freezing Damage
DownloadSpring 2020
The bursting of pipes due to freezing of contained liquid is considerably costly in industrial applications, resulting in over $4 billion in damage over the last decade alone in the United States. This doctoral research program attempted to study the root cause of the failure of pipes due to...

Automated semantic segmentation of NiCrBSi-WC optical microscopy images using convolutional neural networks
Download2022-01-01
Rose, D., Forth, J., Henein, H., Wolfe, T., Qureshi, A.
Convolutional neural networks (CNNs) were used for the semantic segmentation of angular monocrystalline WC from NiCrBSi-WC optical microscopy images. This deep learning approach was able to emulate the laborious task of manual segmentation effectively, with a mean intersection over union (IOU)...

Changing Landscape Coatings for Bioactive Bone Fixation Implants via Flame Spray Deposition
DownloadFall 2013
Owing to the bio-inert nature of load-bearing alloys and the brittle nature of bioactive materials there is a need to develop a composite bioactive material suitable for load-bearing applications. To fulfill this need, a new composite coating of a load-bearing alloy and a resorbable bioactive...

Design and Development of a Novel Tensile Testing Apparatus for Time-Resolved Betatron X-Ray Tomographic Imaging
Download2022-06-01
Arce-Borkent, Alvaro R., Richards, Tait, Senthilkumaran, Vigneshvar, Beier, Nicholas F., Zhou, Le, Moore, John A., Knudsen, K. Steven, Hussein, Amina E., Lipsett, Michael G.
High-resolution imaging of deformation processes in materials under load requires controllable and stable loading conditions and the ability to vary sample orientation relative to the imaging source. A novel tensile testing apparatus has been designed, developed, and characterized for...

Development of a Multi-material Extruder System to 3D Print Hard Thermoplastics, Soft Elastomers and Liquid Metals
DownloadSpring 2019
Functional sensors often consist of rigid parts, soft rubber-like parts, and mechanically tunable electronic components. As part of a larger project to 3D print tunable antennas, it was tasked to develop a printer that could directly produce 3D stretchable electronics with soft and hard...

Spring 2022
This thesis focuses on the manufacturing of high carbide content wear-resistant parts by extrusion- based Additive Manufacturing (AM) based on the principles of Powder Metallurgy (PM). A new manufacturing technique, termed Fused Filament Fabrication of Cermets (FFFC) is presented. First, particle...
