How do you acquire notch sensitivity factor (q) not using the charts? In my design, I have notches with radius 5, and 7.2 mm which are both out of scope of the chart.
@@neutroviolet2918 How though? Surely if there is a notch then the fatigue life will be less than the notch-free fatigue life, so the Kf value has to be greater than 1
Clear. Efficient. Quick. Wonderful video!
Best Lecture in the world on Faigue Stress concentration... Lots of love man!
Thank you for these concise summaries and examples! Sharing with my students.
Wonderful!
not just less boring, brilliant engineering
Your videos are amazing. Thank you. There is a question for the ka table. Values are different than most of the other tables why?
Thank you so much🙏
Can u explain how u found point of loading P = 500, 300mm from the left? did u assume the assembly was loaded in its center?

thanks for this excellent explanation
Perfecto, estoy suscrito
Where did you source the graphs at 3:00?
tq sir
You showed the wrong formula for kf, it's upside down, by your formula kf will be between 0-1
Can you point to the time in which this happens? I already checked the entire video, and I found nothing wrong with any of the Kf expressions.
@@LessBoringLectures check on 1:01 in time! That one (Notched/ Notch-free) should be correct! Make it upside down!

Formula for Kt is wrong
