Acrylic-Polyurethane Based Graft-Interpenetrating Polymer Networks for High- Performance Applications
Alizadeh, Nima (2021-04-05)
In this research, interpenetrating polymer networks (IPNs) based on polyurethane (PU) and acrylic copolymer were synthesized for high-performance applications. Two different polymers with different mechanical and thermal ...
Advanced Characterization of Shape Memory Polymers and Electrospun Conducting Polymers for Engineering Applications
Siwakoti, Midhan (2023-12-06) ETD File Embargoed
Smart materials are an attractive solution to low cost, low weight and high performance applications. They have multifunctional properties that can be controlled by external stimuli such as light, heat and electricity. ...
Development and applications of machine learning frameworks for dynamic emulation of aerospace multiphysics problems and characterization of microstructure
Perera, Roberto (2024-04-23)
Future challenges in aerospace problems, spanning space exploration and military aircraft, demand advancements in several areas, including in-space 3D printing, high-performance missile technology, and rapid structural ...
Development of a one-dimensional moving window atomistic framework to model steady state shock wave propagation
Davis, Alexander (2020-04-10)
We develop a long-time, large-domain moving window atomistic framework using Molecular Dynamics (MD) to model shock wave propagation through a one-dimensional system. We implement ideas of control volume on a MD framework ...
Development of atomistic and concurrent atomistic-continuum frameworks to model shock wave propagation and phonon transmission
Davis, Alexander (2023-04-17)
In the first part of this dissertation, we develop a long-time moving window framework using Molecular Dynamics (MD) to model shock wave propagation through a one-dimensional monatomic chain. The moving window formulation ...
Development of Self-Degrading 3D Printed Polymer Matrix Composites via Moisture Absorption Evaluation
Banjo, Adedotun (2020-07-15)
Polymer degradation is a change in properties such as strength, color, shape, of a polymer or polymer-based material due to the effect of one or more environmental factors. These factors include heat, light or chemicals ...
Dynamic compressive behavior of additively manufactured 17-4 PH stainless steel
Sriram, Siddharth (2023-12-04) ETD File Embargoed
This work focuses on additively manufactured 17-4 PH stainless steel and establishing a correlation between microstructure/printing speed to the dynamic response. Two different methods of additive manufacturing namely Laser ...
High Strain Rate Material Characterization of Lead-Free SAC Solder Alloy and Solder Joint Reliability under Vibration and Thermal Loads
Yadav, Vikas (2022-12-09) ETD File Embargoed
Electronics will experience high and low working temperatures during operations, handling, and storage in severe environments applications such as automotive, oil and gas, aerospace, medical technologies, and defense ...
A Method For Obtaining New Conservation Quantities and a Solution Method For the N-Body Collision
Holmes, Eric (2019-08-15)
Exact, numerical, and perturbative methods are commonly used to solve dynamical systems of equations. Many systems’ solutions cannot be written in terms of elementary functions thus numerical and perturbative solutions ...
A Multiscale Investigation of the Fatigue Behavior of Additively Manufactured Nickel Superalloys
Soleimani Dodaran, Mohammad (2021-11-15)
Fatigue as the most frequent mode of failure among mechanical systems has been the focus of a large part of the research community. Modern manufacturing technologies are developed to address the need for complex geometries ...
Numerical and experimental analysis of Wetumpka impact crater, Alabama.
De Marchi, Leticia (2021-07-19)
Impacts are the most crucial process in the formation of the solar system, since planets and other bodies are considered to have formed by accretion of small objects through collisional processes. By studying craters on ...
Test Methods and Reliability Modeling of Electronic Assemblies under High-G Shock
Dornala, Venkata Kalyan Reddy (2019-10-28) ETD File Embargoed
Electronic systems and sub-assemblies undergo a myriad of stresses during operation in their lifetime. Electronics in consumer, aerospace and defense industries increasingly use commercial-off-the-shelf components in their ...
