Optimum Path Tracking of an Independently Steered Four Wheeled Mobile Robot
(North Dakota State University, 2012)
This thesis studies the navigational control problem for an independently steered and driven four-wheeled ground robotic vehicle, a subset of the larger problem of controlling self-reconfigurable robotic vehicles. A ...
Flow Accelerated Organic Coating Degradation
(North Dakota State University, 2014)
Applying organic coatings is a common and the most cost effective way to protect metallic objects and structures from corrosion. Water entry into coating-metal interface is usually the main cause for the deterioration of ...
Mechanical and Tribological Properties of Carbon Nanofiber Reinforced High Density Polyethylene
(North Dakota State University, 2014)
High density polyethylene (HDPE) is widely used as a bearing material in industrial application because of its low friction and high wear resistance. Reinforcing polymers with the appropriate nanofillers is an effective ...
Mechanical Characterization and Constitutive Modeling of Rate-dependent Viscoelastic Brain Tissue under High Rate Loadings
(North Dakota State University, 2019)
In this dissertation, theoretical, computational, and experimental methodologies are introduced to determine the rate-dependent material properties of the brain tissue. Experiments have shown that the brain tissue is ...
Examination of the Impact of Helmets on the Level of Transferred Loads to the Head Under Ballistic and Blast Loads
(North Dakota State University, 2015)
The main causes of human Traumatic Brain Injuries (TBIs) in war zones are ballistic impacts and blast waves. While understanding the mechanism of TBI and the brain injury thresholds are in urgent needs, efficiency of helmets ...
Fabrication and Mechanical Characterization of Novel Hybrid Carbon-Fiber/Epoxy Composites Reinforced with Toughening/Self-Repairing Nanofibers at Interfaces
(North Dakota State University, 2012)
This research was aimed at fabrication and characterization of novel hybrid carbon-fiber/epoxy composites reinforced with toughening/self-repairing nanofibers at interfaces. For interfacial toughening, continuous electrospun ...
Epoxidized Sucrose Soyate as a Primary Binder in Particleboard
(North Dakota State University, 2018)
Wood composites industry has been growing for decades. However, wood composites have been associated with some health concerns due to the presence of formaldehyde. A promising bio-based resin Epoxidized Sucrose Soyate (ESS) ...
Numerical Simulations of Electrohydrodynamic Evolution of Thin Polymer Films
(North Dakota State University, 2015)
Recently developed needleless electrospinning and electrolithography are two successful techniques that have been utilized extensively for low-cost, scalable, and continuous nano-fabrication. Rational understanding of the ...
The Dynamics of Viscous Droplets near Micro-Patterned Solid Surfaces in Creeping Flow
(North Dakota State University, 2014)
The interaction between droplets and solid surfaces is of great importance in industrial applications, biochemical processes, and fundamental materials research on surface wettability. In this work, a three-dimensional ...
Fatigue Behavior of Flax Fiber Reinforced Polymer Matrix Composites
(North Dakota State University, 2019)
Bio-based flax fiber polymer composites (FFPC) have the potential to replace metals and synthetic fibers in certain applications due to their unique mechanical properties. However, the long term reliability of FFPC needs ...
