Extremely informative video on fatigue loading! Thankyou for bringing this.. Can i please know which Software is this in detail? Please reply at the earliest because I need this for my project work
It's ANSYS Workbench here is the link to download academic version ansys13.ansys.com/release2022R1/ANSYSACADEMICSTUDENT_2022R1.1_WINX64.zip?_auth_=1650997082_677c7ccde9e2da54147efc620abefe14
Thanks for the video, very helful! One comment. You give a practical example in 7:30 "In actual consider the Fatigue Life for a body to be 24.000 cycles and we are loading the body for 1 hour each day, then the expected model life would be 1.000 days". How do you come to this conclusion? Let's say that we have a static loading on a body which lasts some time. For example we have a steel body which takes a load of 10tn, the load remains on the body for some given time and then the load is removed. We make the static analysis in ANSYS and we find that the minimum fatigue life is 10.000 cycles. In practice we put a load of 10tn for 60mins (static loading) and then we remove it. How do we calculate the fatigue life in hours? Thanks in advance.
It does not depend on the time. Fatigue design is based on number of cicles, in the books says that it's independent of the time application of the load for the practice, you can download free the book "Design of machine elements, by Robert L. Mott". I hope i helped you!.
Yes, that's right, fatigue is dependent on number of cycles. In the video and actually on point 7:30, he says that if we get from Ansys a fatigue life of 24000 and the load acts for 1 hour per day, then the model life will be 1000days. If fatigue life is independent of the time force stays on the body, why do we have a fatigue life of 1000 days and not 24.000 days? Remember that we have 24.000 cycles fatigue life.
@@Theo2482 Because you stress the the part 24 times per day (1cycle per hour). If you have a total of 24000 cycles according to this load, it makes 1000 days (24000 divided by 24 cycles per day).
Sir I have 2 questions.1)I got fatigue life max as 1e8. Is it right sir? And 2)I one more thing is that in ur video damage value is more than 1 is it right sir? Will u plz tell sir regarding this.
Biaxiality indicator tells you whether loading experience by the part is pure shear, uniaxial or biaxial. İf Biaxiality indicator value is -1 pure shear condition 0 uniaxial, 1 biaxial condition. For example you get -1 so it is pure shear condition.From the fatigue tool details , you choose stress component as max shear , you will get more accurate and sensitive result for your simulation.
Thanks a lot for this important tutorial...... My question is that...is it possible to know the maximum stress of fatigue analysis at a given number of cycles in ANSYS WB? as it is known we input the alternating stress vs the number of cycles in engineering data from experimental result and we can get the fatigue life of the material that can survive before failure, but how can i know a stress at a specific number of cycles...
One point in the model was subjected to fatigue failure, what would have happen if number of cycle exceed the failure cycle, i mean can't ansys provide prorogation f crack for fatigue analysis? i want to do fatigue analysis for RCC due to earthquake cycle, hence it important to consider above point for me
For example: If I design square-steel-Beam and simulate it by using Ansys/Abaqus to find defection in beam then, does it consider a numerical computation?
Hi, Thanks for the tutorial! I have a quick question, regarding the stress component and the loading in the fatigue tool - Is the stress component the magnitude that you have to specify in the loading data? If not, which are the units? Thanks in advance!
You can find that S-N curves from specific researches just you need to google it. I recommend that you should care about materials's heat treatment process. S-N curve will change after surface hardening or any treatment.
Hello, Can you please provide link to download your geometries so we can practice directly. It wastes time to first draw geometry and then start your tutorial. Thanks
Nice video! What if I would need to create a new material in engineering data? For instance I would need to add the S690QL steel. Do you know any website or any place in the internet that gives you the tabular data for these applications? And maybe data necessary for plasticity settings? Also I have a question related to the loads considered by the fatigue tool: I should make a simulation of a flange with bolt pretensions and some external loads. I don't know how to let the fatigue understand that the bolt pretension should not be considered as a cyclic load! Thank you in advance.
Hi, very good video! I'm starting with my first fatigue analysis and this video explains very well the steps to do. The only thing I did't understand is why you used the fully reversed option when the load is from 0 to -200 N and not from -200 to 200. Wouldn't be better to use the zero based option? thanks
I have to the fatigue analysis for aluminium material, and for that, I need the SN data of the aluminium (pure 99.99%). Can anyone provide me with that?
Can someone explain to me how is it possible that alternating stress in structural steel reach to 3999MPa? i don't understand something can someone explain it to me ? the alternative stress is difference between Sigma max and Sigma min ?
Before someone explains, you first have to explain what are you talking about. In any case, 3999 MPa is out of the world, you must have done something wrong 101%. One possible mistake is material data you've entered are wrong.
can we do fatigue analysis of bike handlebar by this same method? i tried with your method but in fatigue tool the result of the option life was not coming correct, the result showed that the whole part will suffer fatigue at same number of cycle.Can you help me on this? and how can we do vibrational analysis on handlebar in ansys? ,
@@yatinchhabra623 Explicit Analysis is generally preferred for Crash, Impact & Drop. It is very important to understand what simulation outcome is being expected out of any analysis. You can write to engineeringtutorsdesk@gmail.com if you are looking for any simulation to be done.
