A Stochastic Finite Element Analysis Framework for the Multiple Physical Modeling of Filler Modified Polymers
DownloadSpring 2021
Hamidreza Ahmadimoghaddamseighalani
Polymers have various attractive properties (e.g., low volume mass density, low cost and excellent degradation resistance), and hence, they have become essential for a wide range of applications (e.g., aerospace, oil and gas and renewable energy industries). However, due to their limited...

Investigation of Mechanical Properties, Porosity and Geometric Deviation of Lattice Structures Manufactured by Additive Manufacturing
DownloadSpring 2022
This thesis reports fabrication, mechanical characterization, finite element modeling, and geometric analysis of lattice structures. A net-shaped 316L stainless steel lattice structure composed of diamond unit cells was fabricated by selective laser melting (SLM). The cavities in the lattice...

Melt Electrospinning of Shape Memory Polymer: An Initial Examination of the Morphological, Mechanical and Shape Memory Properties of Non-woven Melt-Electrospun Polyurethane Shape Memory Polymer Mats.
DownloadFall 2020
Shape memory polymers (SMP) are a class of smart materials which are able to memorize a temporary shape and recall their original/permanent shape with the application of a stimulus. The electrospinning process has been utilized to produce fibrous SMP membranes from polymer solutions, but this...

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...

Fall 2019
Generating functional parts using additive manufacturing (AM) has many challenges. These can be material- and/or process-based. This is especially true when the produced part is required to withstand or be sealed for pressure due to the potential air gaps inherent to AM processes that generate...
