Bounding Surface Approach to the Fatigue Modeling of Engineering Materials with Applications to Woven Fabric Composites and Concrete
(North Dakota State University, 2011)
It has been known that the nucleation and growth of cracks and defects dominate the fatigue damage process in brittle or quasi-brittle materials, such as woven fabric composites and concrete. The behaviors of these materials ...
Experimental Studies on Infiltration/Soil-Water Movement Processes and Green-AMPT Modeling
(North Dakota State University, 2011)
Experimental studies on infiltration/soil-water movement processes are vital to
better understanding movement of soil-water in the vadose zone. The objective of this
experimental research was to investigate infiltratio ...
Fate and Transformation of a Conjugated Natural Hormone 17β-Estradiol-3-Glucuronide in Soil-Water Systems
(North Dakota State University, 2011)
The objectives of the study were to investigate the sorption and degradation of a glucuronide conjugated natural hormone, 17β-estradio1-3-glucuronide (E2-3G), and its estrogenic metabolites in soil-water systems. Radiolabeled ...
Evaluating the Effects of Rail Preemption Strategies on Highway Safety and Operations
(North Dakota State University, 2011)
Previous research related to signal preemption near highway-rail grade crossings
has emphasized safety considerations, which are paramount due to the severity of potential
train-vehicle collisions. The purpose of this ...
Quantification of the Influences of Subsurface Uncertainties on Seismic Behavior of Shallow Foundations
(North Dakota State University, 2011)
The properties of geomaterials are uncertain. These uncertainties not only affect the
dynamic behavior of the geomaterials, but also significantly influence the complex
nonlinear dynamics between the soil, foundation, ...
Time-dependent Behavior of Various FRP Composites for Structural Applications
(North Dakota State University, 2011)
This thesis represents the long-term behavior of fiber reinforced polymer (FRP)
materials for structural applications. FRP composites consist of high-strength fibers
embedded in an epoxy resin. The long-term investigations ...
