Fused Filament Fabrication of Filled Polymers for Metal Additive Manufacturing

Creator:: Barmore, Brenton
Abstract:: Additive manufacturing (AM) is a relatively new manufacturing technique that can create high complexity parts out of many materials in low volume. The fused filament fabrication (FFF) is the lowest cost AM process and is capable of producing only thermoplastic components. Powder injection molding (PIM) is a high volume low...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Self-adaptive Subsets for Stretched and Rotated Textures in Digital Image Correlation

Creator:: Gao, Zizhan
Abstract:: Digital image correlation (DIC) uses pairs of images, one in a reference state and one after in situ manipulation of the object, to measure full-field displacements and strains by tracking the motion of small image subsets. Subset selection is always a crucial part of DIC technique as it has a...

Risk-based design for multidisciplinary complex systems

Creator:: Farhangmehr, Farzaneh
Abstract:: The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

A Novel Progressive Damage and Failure Analysis Model for Matrix Compression using 3D Continuum Damage Mechanics and Smoothed Particle Hydrodynamics

Creator:: Solanki, Satish
Abstract:: The matrix compression behavior is assumed similar to tension, and many material's elastic and damage parameters are considered equal in tension and compression but experimentally not explored. This assumption leads to unrealistic or very far from the actual behavior of the matrix under compression. Moreover, the pre-existing implemented Abaqus models...

Potential of Genetic Algorithms for Design of Liquid Cooled Heat Sinks Fabricated Using Additive Manufacturing

Creator:: Dokken, Connor B.
Abstract:: The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...

Characterization of Bonding Defects in Carbon Fiber-Epoxy Plates via Thermal Wave Imaging

Creator:: Jolibois, Michael
Abstract:: Thermal wave imaging (TWI), a technology based on heat conduction and radiation through materials, is a relatively new addition to current non-destructive inspections (NDI) systems. Bonding of composites, an extremely important step in manufacturing and repair of laminates, could be affected by defects originating from faulty manufacturing processes or damages...

Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

Fatigue Testing and Analysis of Polymer and Composite Materials Used in Heavy-Duty Trucks

Creator:: Gahan, Kevan
Abstract:: As structural durability analysis is increasingly trusted during the design processes of the automotive industry, more complete and sophisticated modeling of material behavior under both static and dynamic loading conditions is paramount. This is especially true regarding the application of heavy-duty trucks, where modern designs contain large parts such as...
