Computational modeling of trabecular bone indentation and development of a new test method to perform unconstrained load-induced subsidence of an intervertebral body fusion device
(University of Waterloo, 2024-04-24)Intervertebral body fusion devices (“interbody cages”) used in spinal surgeries are susceptible to axial and/or rotational subsidence into the underlying trabecular bone of the spinal vertebrae. Despite the variety of ... -
Design and Characterization of Silicon-on-Insulator Passive Polarization Converter with Finite-Element Analysis
(University of Waterloo, 2005)As optical fiber systems evolve to higher data rates, the importance of polarization control and manipulation steadily increases. Polarization manipulating devices, such as polarization splitters and converters, can be ... -
Development, Optimization and Testing of an Innovative Wedge Anchorage for CFRP Plates
(University of Waterloo, 2018-12-14)Replacing degraded concrete structures can be quite expensive and time consuming; thus, strengthening these structures with fiber reinforced polymer (FRP) elements, such as carbon FRP (CFRP) plates, is more practical. ... -
Effect of Cu and die geometry on the extrudability of AA6xxx Alloys
(University of Waterloo, 2023-12-14)A series of extrusion trials were conducted with AA6xxx aluminum alloys with different Copper (Cu) levels to understand the influence of alloy content, die geometry, extrusion ratio and extrusion process parameters (ram ... -
Finite Element Methods to Analyze Helical Stent Expansion
(University of Waterloo, 2014-07-18)Stent angioplasty or stenting is the standard noninvasive therapy method to address narrowing of the arteries and restore blood flow. Although drug-eluting stents have resolved immediate restenosis (i.e., re-narrowing of ... -
Finite Element Modelling of RC Beams Strengthened with Prestressed NSM CFRP Plate
(University of Waterloo, 2021-04-30)Near Surface mounted (NSM) carbon fibre reinforced polymer (CFRP) reinforcement has become a promising flexural strengthening technique for reinforced concrete (RC) elements. The prestressing of a CFRP plate can be used ... -
Modelling the Dynamics of Mass Capture
(University of Waterloo, 2013-05-01)This thesis presents an approach to modelling dynamic mass capture which is applied to a number of system models. The models range from a simple 2D Euler-Bernoulli beam with point masses for the end-effector and target to ... -
Numerical Prediction of Panel Dent Resistance Incorporating Panel Forming Strains
(University of Waterloo, 2001)This thesis presents a numerical method of predicting both static and dynamic denting phenomena in automotive body panels. The finite element method is used as a predictive tool to assess panel performance prior to ... -
The Numerical Prediction of the Dent Resistance of Aluminum Structural Panel Assemblies
(University of Waterloo, 2001)An examination of static and dynamic dent resistance of structural panel assemblies representing automotive hoods is described in this thesis. Fabricated panel assemblies incorporating typical components of real automotive ... -
Numerical Simulation of Blast Interaction with the Human Body: Primary Blast Brain Injury Prediction
(University of Waterloo, 2014-02-20)In Operations Enduring Freedom and Iraqi Freedom, explosions accounted for 81% of all injuries; this is a higher casualty percentage than in any previous wars. Blast wave overpressure has recently been associated with ... -
Optical MEMS Switches: Theory, Design, and Fabrication of a New Architecture
(University of Waterloo, 2007-06-28)The scalability and cost of microelectromechanical systems (MEMS) optical switches are now the important factors driving the development of MEMS optical switches technology. The employment of MEMS in the design and fabrication ... -
Up-Scaling Distinct Element Method Simulations of Discontinua
(University of Waterloo, 2017-01-20)Pre-existing fractures significantly influence the geomechanical response of the rock mass at the reservoir scale. For geomechanical applications, these natural fractures need to be considered in the mechanical response ...
