I was analysing alloy wheel of car in Ansys, But I had a problem in applying titanium material as the S-N curve parameters was not there. This video gave me a basic idea of the S-N curve and how to calculate it. kuddos professor..!!
Thanks a lot! Qeustions 1. In case of compressoin, is the correction factor same as axial, 0.75? 2. In case of plastics(including composites), are there similar guide lines such as 0.9, 0.5, N=10^3 or 10^6?
sir i confused :) this S-N diaghrams generates by fully reverses stresses ok and if Qm is non zero we use goodman, gerber or soderberg diagrams but this 3 diagrams doesnt consist N(Cycle) how could we calculate the material life from these 3 diagrams. with a specific Qa and non-zero Qm can we jump back to S-N diagram from goodman to calculate N.
Buy him nice equipment to make a better quality video for you and also help him editing it (if you need fancy videos). You Should appreciate the knowledge sharing not bitch about it. If the noise is too annoying why not run a video editing tool on this and remove it?
This is exactly I was looking for. I was asked to make a fatigue analysis for cast component in wind tower. Thank you professor.

Great video. I wish there were more SciDAVis tutorials on youtube in English.
Cody Kellogg Any features in particular you'd like reviewed?
Is this applicable for amorphous materials such as polycarbonate?
As a rule of thumb, how many specimens are required to create an SN curve? Is 8 enough?
Thanks a lot!

Dear Professor, can you please explain about how to obtain the same curve for Aluminium alloys

hello, can you give SN curve allow steel has Sy more than 700 MPa?
What are the formulas to plot for a stress ratio of 0? Or can anyone point me to another video where that is explained..
Horrible static sound in background
