MEC-E8006 - Fatigue of Structures D, 26.10.2020-03.12.2020

Topic outline

• Materials and Assignments
  Find lectures and assignments organized following the workflow of the course.

  IMPORTANT NOTES: 

  • Lecture slides can’t and will not substitute the readings from the course book and other reading material, that should be considered full-fledged course material. Dowling's text book is available online here: https://ebookcentral-proquest-com.libproxy.aalto.fi/lib/aalto-ebooks/reader.action?docID=5173487. Other reading material is available in "Lecture and other material" -folder below. 
  • When delivering assignments (PDF-format, 1 file) do not limit to report only numerical results, but provide brief comments/descriptions on what you are doing (and why). Suggested approach: write first a concise work-flow to reach the final solution, then comment on the main steps.
