Marking scheme

Tasks and guidance

25%

Formulate a 3-D topology optimization problem of your own choice that relates to the field of your study. While the clarity of the problem formulation and correctness of its solution is most important and sufficient for the award of the full mark, an industrial relevance of a problem that you chose is particularly encouraged and will be also rewarded in marking of this assignment

Solve this topology optimization problem for the minimum compliance whilst imposing an appropriate constraint on the volume fraction. You may need to try several different values of the volume fraction in order to obtain a clear structure Put in the report the picture of the obtained material distribution, describe your observations. 20%.

Note that a small variation of an example considered in the tutorials will not be accepted, it should be a sufficiently different problem.

Also, you cannot submit as your problems any of tutorial problems provided by the training materials of Altair Engineering.

15%

Describe the main steps in the procedure of topology optimization that you have used to solve your topology optimisation problem, 10%

Discuss your choice of the parameters of optimization, 5%

20%

As an engineer, interpret the obtained result by and indicate potential for its use, 5%

Sketch your technical proposal for the structure that you have obtained, 5% Draw conclusions from your experience you have gained, 5%

Comments:

Make sure that you specified a sufficiently large design space in which the

optimizer looks for the solution of the problem, e.g. it is suggested not to introduce only a few finite elements in one of the dimensions. Do not impose on the topology optimisation tool the type of structure you expect to see, give it enough design freedom (design space) and see what it comes up with.

Note that if you do not see a clear structure emerging from the solution, you should modify the settings ofthe topology optimization setup (Volume Fraction, Discrete, Member Size, etc.) and include them in the Results part of the report.

20%

Give a brief (about half a page of typed text) opinion on the usefulness (or

otherwise) of topology optimization in your field of study, support your opinion by an example of a relevant application, 20%

Comment: do not repeat the material from the lectures, it should be a personal opinion.
