Determination Of Chemical Notch, KChem On Aluminum And Steel When Subjected Under Slow Strain Rate Test In Corrosive Environment, Joshua Teo Lee Kuok
Determination Of Chemical Notch, KChem On Aluminum And Steel When Subjected Under Slow Strain Rate Test In Corrosive Environment, Joshua Teo Lee Kuok
Masters Theses
When designing for any mechanical components or system, the question would arise as to how the material would react to the loads subjected on it? Would the component survive its service load? How would it react to environmental corrosion? To answer these questions, the technique used in this thesis paper is the Slow Strain Rate Test (SSRT) method. Aluminum and steel were chosen as the material to be tested in this paper. Al 7075-T651, and Al 6061-T651 was chosen due to its wide range of application, high strength to weight ratio and ease of machinability. It is highly used in …
Investigation Of Discrete Element Methods For Stud To Turf Interactions, Justin Rittenhouse
Investigation Of Discrete Element Methods For Stud To Turf Interactions, Justin Rittenhouse
Masters Theses
Artificial turf is frequently used in sports today and attempts to advantageously replicate a natural grass/soil playing surface. Despite numerous advantages, the technology is correlated with an increase in injuries. The concept behind this research is to create and validate a discrete element model (DEM) for the ground/foot interaction through the use of open source software. After validation, the goal is to analyze an arrangement of studs to determine what role stud geometry plays on torque [N-mm] and force [N] generation. The validation data was provided through laboratory experiments. Three football studs attached to a rigid bracket were turned at …
Boat-Lift Design And Analysis, Nathan Schick
Boat-Lift Design And Analysis, Nathan Schick
Honors Theses
A current in production 6000 lb. rated boat-lift is being sold at “Great Lake Lifts”. The lift was tested experimentally and proved to hold at least 8000 lb. The design team successfully modeled the current lift on Ansys to help the customer understand where the weakest points in the design were. Following the creation of the initial lift design, the design team proposed and tested modifications that could be made in order to make the lift more structurally sound. The initial lift had a maximum deflection of 0.43846 inches, a maximum stress of 15880 psi, and a safety factor of …
Benchmarking Of A Single-Cylinder Engine Toward The Development Of A Direct Fuel-Injection System, Michael J. Nienhuis
Benchmarking Of A Single-Cylinder Engine Toward The Development Of A Direct Fuel-Injection System, Michael J. Nienhuis
Masters Theses
In this study, the performance and efficiency of a single-cylinder gasoline, fourstroke cycle engine was benchmarked in support of the Formula SAE student project. The development of an engine test stand, instrumentation, data acquisition, and test plan is described in detail. Experimental results in the areas of engine performance and efficiency are discussed. Physical test data were used to refine a previous model of a single-cylinder, gasoline, direct-injection engine. Results from this effort are discussed and compared to those obtained in a preliminary study. The current work advances the development of more efficient power-train technologies for application in small displacement …
