|Penalties for Late Submissions
• Late submission of any item of coursework will be capped at a minimum pass mark if received up to
one week late. Any submission received more than one week late will be awarded a mark of zero.
• Late submission of referred coursework will automatically be awarded a mark of zero.
• Note: The School operates a strict policy on late submission. Canvas/Studynet marks all work
submitted late, even by one second, as Late, in which case the above late penalties will be
applied. Where genuine serious adverse circumstances apply, you may apply for an
extension to the hand-in date, provided the extension is requested a reasonable period in
advance of the deadline. However, you are warned that lateness due to network congestion
(either at the University or on your local network), difficulty with filenames, poor time
management and similar issues will not be considered as admissible circumstances. For this
reason, you are advised to submit at least one hour before the deadline.
• Explore the underlying physical principles and numerical methods of CAD and FEA techniques.
|Please refer to your student handbook for details about the grading schemes used by the School when
assessing your work. Guidance on assessment will also be given in the Module Guide.
|Guidance on avoiding academic assessment offences such as plagiarism and collusion is given at this

This assignment is focused with the static analysis of an F1 Redbull Front Wing. The students should be
able to model and programme simulations in order to obtain results as realistic as possible at low
computational expense. The students should also be able to validate the results by checking convergence.
It involves the use of a commercial FE (Finite Element) package. CATIA Generative Structural Analysis is
See attached briefing sheet for all the assignment brief details and marking scheme.
• All students must submit their individual report/responds through Canvas/Studynet.
• You should produce a report with a maximum of 10 A4 pages. See attached briefing sheet for
• details on the report. This assignment requires an online submission to Canvas. Reports will
be checked for plagiarism.
• The report needs to be saved with the following filename; SRN_FEA_Analysis.docx and
replace SRN with your individual Student ID number. Your final CAD files as well as Analysis
and Computation files must be submitted as well with your SRN_Filename. Please do not
include your name so that anonymous marking can be used.
|Marks awarded for:
• The assignment contains required tasks must be reported by all students.
• Report must be completed according the instruction provided on Canvas.
• The marking scheme has been specified on the template of the report.
Please see blow document for detail of the tasks.
A note to the Students:
1. For undergraduate modules, a score above 40% represent a pass performance at honours level.
2. For postgraduate modules, a score of 50% or above represents a pass mark.
3. Modules may have several components of assessment and may require a pass in all elements.
For further details, please consult the relevant Module Guide or ask the Module Leader.

Generic feedback will be given during an online lecture.
You will use a commercial FE package to perform an analysis on a Redbull F1 Front Wing subjected to high
compression values. It is suggested that you use the Generative Structural Analysis environment from CATIA
V5 and use of a software different than CATIA is unsupported, thus not recommended.
This assignment is based on a real engineering problem and we hope you enjoy it!
Figure 1 shows the CATIA 3D CAD model of a loaded component to be studied which can be found as part of
the tutorials. Please note the file is 1:10 and for analysis you need to work on real size.
Figure 1 – CATIA 3D CAD model of the Redbull Front Wing
This part is made from steel and needs to be remodelled in such way that while the overall shape remains intact
certain areas are reinforced to take the maximum load.
To reinforce the structure, so that:
1. The maximum displacement measured at any point is smaller than 2 mm with maximum Downforce based on the CFD analysis of your given speed (e.g.116mph)
2. The Von Mises Stress is below the tensile strength,
3. The weight is as little as possible (ideally, the weight should be reduced).
The objective of this assignment is to reinforce the structure while, at the same time, weight is reduced.
You are only allowed to:
1. Change the material 5 times (three given materials and two of your choice)
2. Add ribs/reinforcements at the most convenient locations with the lightest geometry
3. Add fillets to reduce stress concentrations.
|The best design should be as lightweight as possible and should not affect the practicality of
You need to identify the original mass and stiffness and work your way through so that you have a meaningful set of
results to discuss about.
Only the authors’ numbers (SRN) should be shown.
THE REPORT SHOULD NOT EXCEED A TOTAL OF 10 PAGES.
It must be submitted in a word document. Alternative formats will not be accepted.
You must deliver the CATIA files of your final model by uploading it on Canvas. Failure to do so may result
in no marks being awarded.
Presentation is a very important aspect of your report, mostly because of clarity. Use page numbers, headings,
figure/table captions and numbers (and always refer to them in the text), etc.
Above all, the report should look like a proper professional technical document.
DELIVERABLES, OBJECTIVES AND MARKING SCHEME.
The marking scheme (and, therefore, the recommended layout) is presented below. Always provide evidence
(justification, by means of calculations, print screens1, diagrams, etc).
• Print screens of CATIA are recommended to be made using a white background.
• Generate the initial model, showing:
a. Element size and Absolute Sag Values
b. Constraints, and exactly where they are applied;
c. Loads, and exactly where they are applied.
• Check mesh convergence with a few (minimum of 5) simulations by changing mesh size
a. A graph of the maximum displacement vs the number of elements (or mesh size);
b. A graph of the maximum Von Mises Stress vs the number of elements (or mesh size);
c. A clear conclusion about which mesh is the most adequate from your analysis;
d. A picture of the final Von Mises stress distribution, highlighting the most
e. A picture of the final deformation, highlighting the most problematic locations.
• Optimise the model by changing material, adding reinforcements/ribs and/or adding fillets
so that the aims are achieved.
a. A picture of the meshed and optimised model, describing the reasons for the different options and
b. A picture of the Von Mises stress distribution on the optimised model, highlighting the locations
where visible improvements were found;
c. A picture of the vector deformation along the part on the optimised model, highlighting the
occasions where visible improvements were found;
d. Comment on the Von Mises stress distribution and deformation of the optimised model, comparing
these values to the ones obtained in the original model.
NB: If the only change made is in the thickness without any other visible effort, your model will be marked
with zero marks.

|Introduction – Assignment setup
• Clarity of assignment and of background to objectives and scope
• Selection of appropriate method to define the engineering problem, including
justification of why this approach is appropriate
|Results and analysis
• Correct application of the taught tools
• Clear explanation and interpretation of the results

NB: Due to the nature of this assignment, it is very unlikely (not to say impossible) that different
groups of students come up with the same solution. Please take this as an advice on how to avoid
being charged for academic misconduct. We take it very seriously, so please make sure that what
you present is your own work.
