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 ... -
Mechanics of Surface Instabilities of Soft Nanofibers and Nonlinear Contacts of Hydrogels
(North Dakota State University, 2020)The research of this dissertation is formulated in two fields, i.e., the theoretical and computational studies of circumferential wrinkling on soft nanofibers and the swelling mechanics study of a bi-layered spherical ... -
Dynamic Stall Characteristics of Pitching Finite-Aspect-Ratio Wings
(North Dakota State University, 2021)In this study, an experimental investigation was performed to characterize the dynamic stall of pitching wings and provide confirmation of the existence of the arch-shaped vortex for moderate sweep wing. Dynamic stall is ... -
Simulation-Based Optimization and Artificial Intelligence Techniques for Macromechanical and Micromechanical Characterization of Soft Biological Tissues
(North Dakota State University, 2021)Traumatic brain injury (TBI) is a serious health and socioeconomic issue which affects thousands of lives annually in the United States. Computational simulations play an important role in better understanding of the TBI ... -
The Effects of Surface Roughness on the Functionality of Titanium Based Alloy Ti13Zb13Zr Orthopedic Implants
(North Dakota State University, 2021)In this study, the effects of surface roughness on the wettability, cell attachment, and mechanical properties of titanium-based Ti13Nb13Zr orthopedic implants have been investigated. The aim of this multidisciplinary ... -
Experimental Studies of Pulsatile Flow Characteristics of Aortic Models under Normal and Diseased Conditions
(North Dakota State University, 2021)Heart disease is the leading cause of death globally. Aorta is extremely important because of its critical function in blood circulation. Abnormal hemodynamics of aortic valve and arch is related to many severe diseases ... -
Influences of Seawater Flows on the Degradation of Organic Coatings Applied on Offshore Wind Turbines
(North Dakota State University, 2022)The regular protection methods of offshore wind structures consist of the application of two or three layers of epoxy-based coatings with a polyurethane topcoat. The coating systems of offshore wind turbines are mostly ... -
Light-assisted 3D printing of continuous carbon fiber reinforced thermoset composites
(North Dakota State University, 2024)Polymer 3D printing has become an emerging manufacturing technique, due to its design flexibility, however its application to produce structural components is still limited due to the poor mechanical strength and thermal ...
