We have got a fatigue test result serious for T joints. The material was 3CR12. The load was bending.
The result was very strange, because in the case of r=-1 (assimetric ratio) the fatigue strenght limit + mean stress (in this case szigmamean= 0) was higher than in the case of r=0.
Does somebody know similar test results or it is an error?
Thank you!
Ervin
