T73S04 (Creep-Fatigue Crack Initiation) Tutorials Menu Page

The links to pdf's below provide the complete transcript of the presentation notes used in the tutorial sessions for T73S04. The first item is a summary of the topics covered broken down by session. The second listing provides the associated homework questions. Finally the third listing provides my answers to the homework questions. The latter are not generally made available.
