Fracture Initiating Mechanism in Additively Manufactured 17-4 Stainless Steel
(North Dakota State University, 2022)
Additive manufacturing provides exceptional geometrical freedom to the designers and enables the production of parts that cannot be made through subtractive processes. Defects in additively manufactured (AM) metals are ...
Artificial Intelligence-Empowered Structural Health Monitoring, Damage Diagnosis, and Prognosis of Metallic Structures
(North Dakota State University, 2022)
etallic structures are the key backbone of the society and economy, which are often subjected to different types of loadings resulting cracking, corrosion, and other material discontinuity, and affecting structural integrity ...
Hygrothermal Effects of Air Cavities Behind Claddings on Building Envelopes
(North Dakota State University, 2022)
Air cavity behind claddings within building envelope provides an approach to mitigating building moisture-related issues as well as improving the building’s thermal performance. However, studies in literature commonly ...
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 ...
Investigating the Influences of Ingredients, W/C Ratio and Dispersion Methods for CNT Modified Smart Concrete
(North Dakota State University, 2022)
Carbon nanotubes (CNT) have excellent electromechanical properties and can be added into cement using appropriate dispersive means to produce CNT-modified cement-based smart materials (CNTCS). This study investigates how ...
Optimizing Selection and Implementation Protocols of Lean Construction Tools and Techniques for Rapid Initial Successes
(North Dakota State University, 2021)
Lean construction (LC) has been considered as one of the most promising project management philosophies to overcome low productivity and excessive waste issues impacting the construction industry. Despite strong philosophies ...
Identification, Categorization, and Prediction of Drought in Cold Climate Regions
(North Dakota State University, 2021)
To mitigate drought losses, identification, categorization, and prediction of droughts are essential. The objectives of this dissertation research are (1) to improve drought identification in cold climate regions by ...
Evaluating the Safety and Mobility of the Cumulative-Anticipative Car-Following Model for Connected Autonomous Vehicles
(North Dakota State University, 2020)
The advancements of vehicle automation are progressively improving resulting in safer driving environments in addition to more efficient mobility and fuel cost savings. However, autonomous and connected autonomous vehicles ...
