Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional spinal deformity with lateral curvature and axial vertebral rotation affecting 1-3% of adolescents. Bracing is a proven non-surgical treatment aiming to stop curve progression. Literature has shown that brace wear time affects brace...
Additive Manufacturing of Shape Memory Polymers: Effects of Print Orientation and Infill Percentage on Mechanical and Shape Memory Recovery PropertiesDownload
Material Extrusion Additive Manufacturing (MEAM), also known as Fused Deposition Modeling (FDM), is a manufacturing technique in which three-dimensional objects are built. These objects are built by repeatedly extruding thin layers of molten materials through a nozzle in different paths and...
Polypropylene (PP) is a thermoplastic polymer and is one of the most widely used polyolefin polymer, which is a well-known semi crystalline polymer. Plastics such as polypropylene are commonly used for different applications and purposes due to their versatility; however, it should be noted that...
Cutting the pavement to install a small diameter utility network, such as flexible pipes, conduits or telecommunication lines, is a common practice in urban areas. The last 200 meters of installation is known particularly difficult to deliver, with obstacles both above and below ground to...
Strain aging of microalloyed steel pipes, manufactured for oil and gas transmission, can occur during the anti-corrosion fusion bonded epoxy coating process (180°C - 250°C) and/or during long term storage or use. The primary mechanism of strain aging involves the segregation of interstitial...
Evaluation and prediction of the tensile properties of continuous fiber-reinforced 3D printed structures composite structuresDownload
Three dimensional (3D) printing is a technique conventionally used to manufacture prototypes. Commercial desktop 3D printers have become available which produce functional 3D printed parts. The MarkOne by Mark Forged manufactures printed structures reinforced with continuous Carbon, Fiberglass or...
Experimentally Determined Mechanical Properties of, and Models for, the Periodontal Ligament: Critical Review of Current LiteratureDownload
Introduction. This review is intended to highlight and discuss discrepancies in the literature of the periodontal ligament’s (PDL) mechanical properties and the various experimental approaches used to measure them. Methods. Searches were performed on biomechanical and orthodontic publications (in...
Cementitious binders have been widely used to improve the mechanical, hydraulic, and physical properties of soft soils by deep soil mixing and jet grouting in the past 50 years. However, the majority of previous investigations are limited to the stabilization of very soft clays in marine...
This thesis presents work performed to improve the work hardening behaviour of an X80 microalloyed steel through various Interrupted Thermal Treatments (ITT). The aim of this work was to determine the relationships between thermal history, microstructure and mechanical properties through both...
There are growing demands for energy throughout the world. In order to meet the rising energy pressures of the future, renewable sources are required. One approach to resolve this problem is organic photovoltaics (OPVs), which offers a potential low-cost energy solution for the future. Before...
