Microwave Torrefaction of Natural Fibers for Incorporation into Engineering Thermoplastic Biocomposites
(North Dakota State University, 2015)
Little work has been done in the area of engineering thermoplastic biocomposites due to the increased processing temperatures which induce degradation of biomass. Torrefaction has been identified as an effective means of ...
A Micromechanical Procedure to Characterize the Effect of Interface in Fibrous Composites and Brain White Matter
(North Dakota State University, 2012)
A micromechanics computational algorithm for fibrous composites including fiber, matrix and interface is introduced to study the impact of interface on composite behavior. The domains are modeled by finite elements with ...
Potential Applications of Flax Fibers
(North Dakota State University, 2018)
There has been a substantial increase in the usage of natural-fibers and biodegradable polymers due to the needs of the environmental sustainability. The use of natural fibers is inclusive of wide range of applications in ...
Hybridization of Bast Natural and Synthetic Fibers in Thermoplastic Composites
(North Dakota State University, 2019)
In recent years, the use of natural fiber-reinforced composites in more advanced applications has grown substantially. Applications of high strength require high mechanical properties. An effective method for increasing ...
Experimental Study of Effects of Leading-Edge Structures on the Dynamic Stall of a Vertical Axis Wind Turbine Airfoil
(North Dakota State University, 2020)
Vertical axis wind turbine, developed as one of the main methods to utilize the wind energy, has a promising future; however, the major issue to limit its performance is the uneven loading on the blade during operation. ...
Dynamic Stall Characteristics of a Pitching Swept Finite Aspect Ratio Wing
(North Dakota State University, 2019)
This research will investigate various swept wing models, designing the mechanism for their pitching motion and control, designing wind tunnel implementation, and performing data measurements and analysis using particle ...
Unsteady Aerodynamics and Turbulent Near-Wake Characterization of Static and Rotating Cylinder Sytems
(North Dakota State University, 2018)
External flows around bluff bodies have been broadly investigated due to their great importance in engineering applications including aircraft and missile development, marine and naval structures, vehicle aerodynamics, ...
Cavitation Inception and Contaminant Effects
(North Dakota State University, 2014)
Within a liquid, it is possible to lower the pressure to a point in which the nuclei gas bubbles will cause cavitation inception. During this drop in pressure, at constant temperature, the bubble tension will increase to ...
Dynamic Modelling for the Path Tracking Control of a Four-Wheel Independent-Drive, Four-Wheel Independent-Steer Autonomous Ground Vehicle
(North Dakota State University, 2017)
Robots that can be reconfigured to perform more than one task would be to consumers. The Four-Wheel Independent-Drive, Four-Wheel Independent-Steer (4WD4WS) robot is well suited for the role of reconfigurable robot due to ...
Robust Control of Skid Steered Robotic Vehicles on High Friction Surfaces
(North Dakota State University, 2015)
The autonomous control of unmanned ground vehicles (UGVs) is a growing research area. Skid steered UGVs are desired because of their simple control inputs, however the control algorithm requires complex dynamic analysis. ...
