Final Project
Identify an engineering materials mechanical failure relevant to both this course and your
specialized area of research. Put yourself in the shoes of the first scientist tasked with
identifying the root cause of the failure – this means you don’t know everything that is
currently known/published about this failure; you just know what happened and you have
some background information. Develop a research approach for identifying the root
cause of the failure. Consider the following when developing your approach:
•
What is known about the system that failed, the environment in which in
failed, the testing that was done on the system before it was constructed?
What are the fundamentals of the system?
•
What factors (external stresses, environmental factors, etc.) were present?
Could any of them have contributed to or caused the failure? How so?
•
Which factor(s) do you hypothesize as being the most significant contributors
to the failure? Why? How does this factor(s) contributes to the failure?
•
How can I test the effects of these aforementioned factors on my system? Can
I isolate the effects of one factor?
•
Are there models or theories that can confirm my hypothesis? How can I
implement them?
•
Proving your hypothesis not only requires confirmation of your ideas, but also
disproving competing ideas. So what are some competing hypotheses? How
can I test them?
The project deliverables are:
•
Topic Proposal. This should take the form of an abstract (~300 words).
Discuss the topic you have selected; provide some background information;
explain the societal impact of the failure; suggest your initial hypotheses.
DUE: 12 November
•
Presentation of your Research Approach. This should be similar to the
doctoral thesis proposal. Each student will have 20 minutes + 5 minutes for
questions.
DUE: We will hold the presentations during finals week.
