Bu çalışmada, bitkisel lifler kullanılarak üretilen biyo-kompozit malzemelerin mekanik özelliklerini karşılaştırmak ve geliştirmek hedeflenmiştir. Biyo-kompozit numunelerin üretiminde takviye elemanı olarak kabak lifi ve jüt lifi kullanılmıştır. Numunelerin üretimi için matris m…
Asphalt is an amorphous material whose mechanical performance relies on viscoelastic responses to applied strain or stress. High quality pavement can enhance the commute experience and also can reduce the risk of accidents as well as preventing air pollution. Furthermore, it als…
Material extrusion based additive manufacturing (AM) technology, such as fused deposition modeling (FDM), is gaining popularity with the numerous 3D printers available worldwide. FDM technology is advancing from exclusively prototype construction to achieving production-grade qu…
Understanding of extensional flow mechanism is utmost important for the efficient operation of many industrial processing such as fiber spinning, extrusion, injection molding, and electrospinning, particularly if these involve non-Newtonian fluids such as polymer fluids, gels, f…
Currently, titanium alloys are used in a variety of applications, including defense, aerospace, biomedicine, and even common consumer products such as bicycles and golf clubs. In many applications such as the landing gear of aircraft and geothermal energy production, titanium co…
Slow crack growth (SCG) is a time-dependent brittle-type failure that polyethylene (PE) pipes suffer from when under low stress levels. In order to achieve a required lifetime of minimum 50 years, a deep understanding of material's properties is needed. The general accepted mech…
This study evaluated the properties and performance of field-produced HMA and foamed WMA mixtures from the Bravo Ave project in Reno, Nevada in comparison to respective laboratory-produced mixtures utilizing the same materials and mix design. Each mixture contained 15% RAP and w…
Recent research has demonstrated a strong correlation between the differentiation profile of mesenchymal stem cells (MSCs) and scaffold stiffness. Chitosan is being widely studied for tissue engineering applications due to its biocompatibility and biodegradability. However, its …
Pipe subjected to internal pressure has its highest mechanical stresses in the tangential direction. For a proper design of pipes, it is of paramount importance to relate the stresses to the right material properties. Currently there is no convenient standard test method to dete…
The building and construction industry is the third-largest producer of CO2 in Canada. Additionally, emissions from this industry are expected to go up by more than nine megatonnes of carbon dioxide equivalent (Mt CO2 eq) by the year 2030. As such, we need to find ways to reduce…
Standard pullout tests (e.g. 200 mm cubes) with a short embedment length have shown a significant reduction (80% loss at 200 °C) in the bond strength of GFRP bars at high temperatures. More detailed bond behaviour of glass fibre reinforced polymer (GFRP) reinforcing bars has bee…
Poly(lactic acid) (PLA) is a well known biodegradable polymer that can be applied for short term packaging in food and cosmetics. However, PLA is brittle, which significantly limit its industrial packaging applications. Blending PLA and other polymers serve as one of the alterna…
Need for a six degrees of freedom test platform to be used in the inertial stabilization development tests of turrets, remote controlled weapon systems or sight systems is present in modern military technology development. To address this research issue, within this thesis study…
The long-term creep behavior of shale has become a major concern in different engineering applications, which reduces oil and gas production of shale reservoirs and triggers devastating landslides. While indentation creep tests at the nanoscale can reveal creep responses of sing…
