report for bicycle helmet
In your report, you are expected to mention the following points:
o Importance of the topic and why you chose it (e.g. I chose digital keyboard keys
because I need to fix my brothers keyboard and trying to find cheapest and best
performing material, or every year this many people dying from heart disease so I
chose heart stent material etc.). Your chosen topic has to have a meaning for you.
If your topic is not original and no purpose is clearly stated in choosing that topic,
I will cut marks.
o Properties you are looking for in that component (e.g. it has to absorb energy, it
has to be strong and stiff, but it has to be cheapest or environmentally safest
option, etc.) You need to prepare the table for the translation step.
o Your approach to the material selection problem, your material indices (don’t
need to show derivation), the material selection charts you chose to apply your
material indices, and candidate materials. If you choose wrong material indices or
missing material indices, you will lose significant points.
o Supporting information from literature to support your material of choice (e.g.
after my material selection procedure I chose carbon-carbon composites to be the
best option and my literature review shows that this indeed is the commonly used
material for this application). I’ll ask you information to check if you did literature
review and if you cannot answer my question, you will lose points.
o How you chose to process your material of choice using process selection charts
and literature information supporting that process.
o You will need to generate the charts yourself using the software. I won’t accept
print out charts. Be creative and generate desired charts for your own problem.
Your report might cover the following titles (minimum 4 pages):
ü Introduction
o The reason you chose this topic, and the importance of it etc.
ü Required properties for the component
o Summarize all the properties that your material should have for that application
supporting with the literature (e.g., non-toxic, strong, high fracture toughness,
high fatigue life, high service temperature etc. together with reasons behind it.)
ü Materials selection procedure
o Design requirements in a table (function, objective, free variables, etc.)
o Material index and its derivation or refer to appendix for the correct index
o Application of material indices on charts
o Candidate materials and literature support
ü Processing selection
o Use process selection charts in order to make your process selection
Cost and environment
o Talk about the cost of your material and compare it with other possible candidates
using cost charts or literature findings.
o Talk about the environmental effects of choosing this material. e.g., Is it
recyclable?
o Use embodied energy charts or embodied energy data from appendix to rank
materials
ü Conclusion
o A paragraph of summary
conducted literature search.

acceptable. If you copy exactly your slides, you will get low score. The content of
presentation and report are the same but report should include extra information
whereas presentation should just be the summary of your report.
your material index to the chart, the best material for example can be composites. But
charts don’t specify what type of composite it can be so you will do literature search and
support your finding and at the same time you can find a more specific name to your
composite material selection such as Kevlar fibers in epoxy etc. Or charts might guide you
to Ti alloys but with literature search you can find a specific Ti alloy
