Determination And Validation Of Mechanical Properties Of Materials And Substructures, Karl Bates
Determination And Validation Of Mechanical Properties Of Materials And Substructures, Karl Bates
Williams Honors College, Honors Research Projects
The nature of this project is confidential and cannot be disclosed in detail. Generally, this project involves the manufacturing of an original design, which is subjected to a variety of tests – including tensile, compressive, bending, fatigue, and environmental testing, as well as qualitative destructive tests – to determine the mechanical properties of the component. This testing data compares with values predicted using Finite-Element Analysis. The validation of predicted FEM values is crucial to the success of this component, as it is designed for lifecritical applications. If test results indicate poor structural performance, considerable redesign will be necessary.

The need for hands-on and face-to-face experiences in the engineering classroom is very great. The equations, principles, and concepts can all be learned, but without the visual and tactile application, these don’t always sink in or become concrete. A small-scale tensile test machine was designed, sourced, manufactured, and tested for the purpose of being applied in classroom settings to provide this experience to engineering students. Extensive research was performed concerning tensile machines on the market, the essential elements of which are the load cell, grips, crosshead, extensometer, motor, and frame. The raw materials for the frame were purchased and drawings …

Jominy Hardenability Tester With In-Situ Heating, Luke Allen
Williams Honors College, Honors Research Projects
This project centers on building a Jominy Hardenability tester with In-Situ heating for the manufacturing lab at the University of Akron. A new process and setup will be designed using engineering concepts in order to make the testing more efficient and safer for the teaching and testing of metal hardness. The current Jominy testing setup has efficiency issues within the transfer of specimen from induction heater to testing rig. Our design will simplify the design by creating a test rig that removes the traveling aspect of the specimen which will limit the amount of premature cooling done and will be …
