Interfacial Characterization of Fibrous Composites by Cohesive Zone Method
(North Dakota State University, 2013)
This work deals with investigation of the interface between unidirectional E-glass fiber and epoxy matrix composites. The two parts in this work are: 1. A periodically constrained finite element (FE) model built as a ...
A Study on the Processing Characteristics and Reinforcing Potential of Natural Fiber Mats
(North Dakota State University, 2012)
Limited information exists regarding the processing parameters and extent of reinforcing potential natural fibers have in polymer matrices. The five natural fiber mats studied were low shive flax, mid shive flax, high shive ...
Numerical Methods for Fractional Optimal Control and Parametric Problems
(North Dakota State University, 2011)
Fractional derivatives (FDs) or derivatives of arbitrary order have attracted considerable interest in the past few decades, and almost every field of science and engineering has applications of fractional derivatives. ...
Potential for Industrial Vehicle Electrical Applications
(North Dakota State University, 2011)
Synthetic metals are a branch of material science that deals with conducting organic molecules.
The quantum mechanics of these materials show that doping can fundamentally
change the conduction method and significantly ...
Stress-Function Variational Method and Its Applications in the Strength Analysis of Bonded Joints and Hard Coatings
(North Dakota State University, 2011)
High concentrations of interfacial stress near the adherend ends are primarily
responsible for the debonding failure of bonded joints, such as those structured extensively
in civil and structural engineering; aeronautical, ...
A Molecular Dynamics Study of Mechanical Properties of Carbon Nanotube Polymer Composites and Graphene Nanoplatelet Polymer Composites
(North Dakota State University, 2010)
Carbon nanotubes have been the main focus in science and engineering fields lately
for their extraordinary properties. But carbon nanotube fabrication process is very
expensive, particularly for reinforcements and ...
Performance Analysis of an Advanced Emission Reduction Technology Engine During Diesel-Hydrogen Dual Fuel Operation
(North Dakota State University, 2011)
The primary objective of this study was to determine the capability of a CAT
engine controlled by an advanced combustion emission reduction technology
(ACERT) electronic control module to operate in a dual fuel mode. A ...
Numerical Simulation of a Direct Expansion Geothermal Heat Pump Using Carbon Dioxide in a Transcritical Cycle
(North Dakota State University, 2011)
Many of the synthetic refrigerants used in heat pump and air conditioning
systems are potent greenhouse gases. In light of the increasing concern regarding
climate change, there has been an increased interest in natural ...
Foaming Kinetics of Closed Cell Rigid Polyurethane Foam
(North Dakota State University, 2010)
Rigid polyurethane foams have shown promise in several applications as a means to
reduce weight without compromising structural properties. Information about the
chemical formula of the liquid components, the reaction ...
Performance Prediction Model for a Hybrid PVT System
(North Dakota State University, 2010)
Photovoltaic cells convert, depending on the cell type, 6-18% of the incoming solar
radiation into electricity with a higher percentage converted into heat. The heat in turn
affects the cell temperature which has direct ...
