Exams

The elastic analysis part will be examined by twelve multiple choice questions. The plastic analysis part will be examined as the discontinued course CIE4150. On the website of this course you can find old exams and answers. You need to practice at least three days with these old exams. Experience shows that it is not really possible to pass the exam without practicing.

During the exam, it is allowed to use readers, handouts, books, notes, calculator, laptop computer, tablet, internet and ChatGPT.
All software is allowed with the exception of the programs Mp (icozct.tudelft.nl/TUD_CT/software/mp/) or Slab (www.limitstate.com).
Obviously, during the exam it is not allowed to communicate information with other people than the teacher.
