Literature regarding the appearence of cracks in steel. Thermal, pressure fatigue
Fri, 2011-01-14 09:45 - danielel
Hello!
I am wondering if anyone could recomend som literature for me to get my hands on.
If there is any literature regarding how the appereance of a crack in a piece of thin metal (~0,5mm - 1 mm) could be related to pressure fatigue or thermal fatigue.
Does the crack due to thermal fatigue have a specific appereance and so on. I need get my hands on practical pictures and so on, not equations.
Are there any signs in the vicinity of the crack that is indicating that this could be due to pressure fatigue.
Any help is much appreciated.
Thanks
Daniel

Literature regarding the appearence of cracks
Hi Daniel,
fatigue in general is quite a big subject. Are you looking for literature on fatigue crack initiation or more into the crack propagation period? And you also have differences between High Cycle Fatigue and Low Cycle Fatigue. I would suggest that you go through the papers of K.J Miller. Especially the one called: Metal Fatigue: Past, present and future.
But you need to be more specific, what size of crack you want to investigate and what's the loading you are having. The orientation of tha crack, the crack path, as well as the crack speed can tell you information about your loading system.
