Exploration Of The Mechanical Properties Of Both Ridged And Inflated Drop Stitch Fabric Material, Roberto Felicissimo
Exploration Of The Mechanical Properties Of Both Ridged And Inflated Drop Stitch Fabric Material, Roberto Felicissimo
Dissertations and Theses
The mechanical properties of drop stitch fabric materials in tension and shear has been investigated for use in designing structural applications such as ship construction, modular buildings, inflatable structures, aquatic vehicles, sporting goods and temporary field equipment installations. The goal of testing is to improve the understanding of the mechanical properties, which can aid in application development for structural deployments using these unique materials. The benefits of using rigid drop stitch fabric panels in ship and building construction are their light weight and rigidity. The epoxy resin infused fabric is corrosion and degradation resistant while providing a more robust resistance …
Morphology Of Brain Sulci Trabeculae And Its Effect On Brain During Impacts, Sharlin Anwar
Morphology Of Brain Sulci Trabeculae And Its Effect On Brain During Impacts, Sharlin Anwar
Dissertations and Theses
Traumatic brain injury (TBI) is an intracranial injury caused by direct contact or non-contact head impacts to the brain. TBI is a major problem that accounts for high incidents of hospitalizations each year. Thus, it is important to understand and predict the occurrence of TBI in an impact. It has been shown that the subarachnoid space (SAS) trabeculae play an important role in damping the effect of an impact, thus reducing the injuries. However, the influence of sulci parameters and the sulci trabeculae in TBI due to impact is unexplored. Studies have shown that inclusion of sulci in brain models …
Performance Of Self-Excited Energy Harvesters With Tip Bodies Of Non-Circular Cross Section Shapes, Joan Manuel Gomez
Performance Of Self-Excited Energy Harvesters With Tip Bodies Of Non-Circular Cross Section Shapes, Joan Manuel Gomez
Dissertations and Theses
An experimental study on the performance of self-excited energy harvesters with non-circular tip body shapes has been performed. The two tip body shapes analyzed correspond to a half cylinder and a square cross section. Experiments are carried out in the wind tunnel to record the voltage output of the harvesters at different free stream velocities. The presence of the aeroelastic galloping instability was detected by the behavior of the transversal tip displacement of the harvester as well as the coupling of the motion and shedding frequency from the bluff body. The effect of tip mass, free stream turbulence, tip body …
An Experimental Study Of Subcooled Flow Boiling At Elevated Pressure In An Annular Flow Channel, Pervej Rahman
An Experimental Study Of Subcooled Flow Boiling At Elevated Pressure In An Annular Flow Channel, Pervej Rahman
Dissertations and Theses
An experimental setup was developed to study the region of subcooled flow boiling. Multiple studies were carried out to investigate the effects of liquid velocity, pressure, and temperature on the boiling heat transfer of subcooled fluid flowing through a heated annular channel. Water was used as the working fluid and principle of Ohmic heating was used to raise water temperature. The system pressure, heat flux, & mass flux ranged from 101 to 912 kPa, 19 to 155 kW/m2, and 83 to 332 kg/m2-s, respectively. This report contains boiling curves, heat transfer coefficients of various studies and a description of the …
