It is really nice being able to re-live the lectures that I once sat through, explained in a slightly different way. It's like all of this knowledge that I haven't used since the final exam rushes back to me at once! Almost makes me wish I had pursued a career in machine design.

very clear, and also the presentation is very good. the quality of the the video is well above the online classes of my university and I paid like $5000 for each course
I'm an aero major and I'm learning this stress analysis stuff for my job because I didn't learn it in my major. I remember in those undergrad classes, I probably only truly paid attention to less than half of what the professor said in class. Yet, watching this video, I'm surprised that I found myself completely focused throughout the whole thing. Whatever you're doing, it works!
Good refresher...everyone at the refinery talks about Fatigue. I needed a refresher course since its been a while and not much of an emphasis in Chemical Engineering.
I'm currently taking Design Machine Elements at the University of Connecticut and at this point I am no longer going/watching my professor's lecture videos. I wish I had found your channel at the beginning of the semester. Thank you for doing all of this, I will gladly share your channel with my classmates!

@@TheBomPE Thank you much. Hey I had a quick question in regard to the relationship you obtained for sigma_f^prime from the SAE handbook. I am using shigleys 11th addition and I cant find that information. Was curious to know if I can use that relationship in regard to a specimen that has a machined surface where I have already obtained the modified endurance limit? Also, do you always add 50 ksi to the specimen's ultimate tensile strength or does that value change with respect to different steels' ultimate tensile strengths?
Yes they made significant changes to the 11th edition. To understand all of the steps I took in this video, it helps to have a 10th edition to reference. The short answer is that yes, you just add 50ksi (constant).
you are God sir, I'm seeing the lectures on every topic I search for. Infact the lectures are more than the topics I search for. How it is possible to be perfect in all fields like Civil, Mechanical and Electrical departments.
Thank you! I'm glad you enjoyed it! I have two courses that I teach out of this text (Shigley), and I have a good number of videos presenting this material, organized into these playlists: MEEN361: th-cam.com/play/PL1IHA35xY5H5AJpRrM2lkF7Qu2WnbQLvS.html and MEEN462: th-cam.com/play/PL1IHA35xY5H5KqySx6n09jaJLUukbvJvB.html Check them out if you are interested! Thanks for watching!
My apologies! I didn't mean to say or imply that civils never do fatigue analysis. I probably should have been more focused on saying that our ME program at Louisiana Tech features a lot more fatigue analysis than the civil program does. Thanks for the feedback!
So great lecture! As all your lectures. To learn new or to refresh some old knowledge. So helpful for engineers from other fields, Civil in my case. Thank you!
Thanks for making video of about fatigue as it will be very help for me in my study. I would like to request you to please explain little bit about Basquin’s law
It seems that the gyroscopic effect was completely ignored in the loading model in the last example ... In the classic fatigue setting of Völler, the model is different and includes a steady mass that creates a bending moment for a rotating shaft.
Thanks, doctor I have a question ? When analyzing metal fatigue, should we prioritize the first plastic strain or the equivalent plastic strain? How might this choice impact the accuracy and efficiency of our results?
Is this considered the stress-life method? My lectures only covered applying Goodman's Criterion with adjusted endurance limit right out of the gate, and I am a bit confused at this point. My textbook(Shigley's 11th ed.) does not solve in this way, rather applies an adjusted von-mises stress without great detail of any underlying development of the equations. It is extremely hard to find supplement for this topic. Your lecture helped me tremendously, but there are gaps in connecting the relation with Von-Mises stresses.
If you found this video useful, consider helping me upgrade the old tablet PC I use to create these videos! Thanks! www.gofundme.com/help-replace-my-2011-tablet-pc
Fantastic Lecture!! can you share me what are using to draw all these lines and write equation? is it a tab or something else cause i am also planning to give lecture to undergraduate students.Thankyou
I use a Fujitsu tablet PC running onenote 2007 and Camtasia 9. The tablet is a T901 that has good specs (Gen2 i7, 16GB ram, NVIDIA graphics, wacom digitizer). Best of luck with your class!
Great presentation, thank you! I've followed the methodology for my case (a load monitoring pin made of 17/4PH to condition H1150D) and I used the maximum calculated stress as the Von Mises stress (in my loading case). Sf(prime)1000 is far bigger than my calculated stress, which would take me into the high cycle region. The formula for "a" (high cycle) contains Se (fully corrected). Where do I take that one from? I couldn't find anywhere the S-N curve for that material and condition. Am I on the right path? Many thanks for your support.
Hi, should we consider the marin factors for calculating the stress at 1000 cycles, as we are considering it at the million cycle. also for the Ultimate stress. while drawing the SN curve for a part. in other words the curve will shift down by the factor of product of all the marin factors. Please clarify.
I'm a student studing mechanical eng. then I have a question about fatigue life. For example, when predicting the fatigue life of a rubber in a rubber mount, does the change in the mass of the cradle affect the fatigue life? (cradle is base frame and it is connected rubber mount) otherwise this video was GOOD
I use a Fujitsu T901 with a gen 2 i7, 16GB of ram, an nvidia graphics chip, and a wacom digitizer. I use Microsoft onenote 2007 for inking and camtasia for capture and editing. Thanks for watching!
There are fatigue strength coefficients listed for several types of materials in table A-23 in Shigley. If you are dealing with steel and you do not have specific data available for fatigue strength coefficient, you can use the SAE estimations cited in equation 6-11 in Shigley (as I did in the example in this video). If you have an experimental SN curve for the specific type of material in question, you can use equation 6-9 in Shigley as a model and do a curve fit to find the fatigue strength coefficient and the fatigue strength exponent. I'm not sure what you are starting with, but these are some possible answers. Thanks for watching!
Hello, i have a question that came up in my mechanical exam and it was 'Explain how fatigue affects the behavior of engineering materials, then explain how and why fatigue affects the stated behavior'. I'm confused
Sir, have you solved a beam with two end fixed , support at any point in the middle and loaded at multi points with 3 reactions yet? This could be a statically indeterminate problem.
No, I don't have a problem like that recorded yet. It looks likely that I will be teaching a course here at Louisiana Tech University that covers statically indeterminate problems like that within the next year or so, so I'll probably get to it sometime relatively soon!
Sir! I am solving one fatigue analysis problem in Hypermesh using S-N method. So I needed S-N curve data so could you suggest where can I get all these data for different materials?

TheBom_PE many thanks, I think I will switch to surface, since I tried and it is really amazing. I am a paper guy and always need to write to explain and it is at the moment the only device that gave me that feeling. Thanks for sharing your experience!
You're right, I did neglect direct shear. Fortunately direct shear would only add about 1.34ksi of shearing stress. Combining that with bending stress using DE theory would bring the von-mises stress to about 107.46ksi as opposed to the 107.43ksi I used in the example. I think it is OK to neglect direct shear in this case. Thanks for watching!
Thank you! th-cam.com/video/ZsIwEp574ho/w-d-xo.html Can not understand how Sigma F can be bigger than Sut (+50ksi)? IMHO Sigma ultimate is always have to be biggest value of all as it is a result of shortest test of all discussed here... (only one loading)
@@TheBomPE Dear Professor, I couldn't trace your next video, since you didn't mention any module numbers. I just skipped lecture 20, 21 and watching 22 Marin Factor and Stress Concentration.
Ah, I understand now. There aren't any videos between this one and the one about Marin factors. You probably saw the numbering at the top of my notes... these are the meeting numbers where I began those lectures in the term when I recorded them.
