SOLIDWORKS Simulation - Fatigue Analysis

How long is too long? If you’re interested in predicting the life of a product, and whether the material may fail after repeated uses, this video is for you. Watch this tutorial and learn how to run a fatigue analysis on a SOLIDWORKS model to estimate the damage due to repeated stress events.

Great Video! What is the best stress to use in the fatigue tool - von misses or principle P1? How does Solidworks account for Stress Gradient Effects in fatigue? I know you can use a Goodman model in Solidworks Fatigue, but what about the Findley model that accounts for shear stress causing crack initiation?

. Good video I hope to know. The fatigue study is included in the model after 31 % damage test will fail or withstand?

Could you tell me which website is good to find S-N curve data? I'm trying to do a fatigue analysis for a FSAE car shift gear, but I could not find right S-N data for the project in the solidworks because my alternating stress for the model is very low

Very helpful video! If you are dealing with low cycle fatigue case, then strain-life is a better approach. Is a strain-life approach possible in Solidworks fatigue study? If not, you would need to note the highest strain in the static study and compare it to the expected strain at failure (found by using the Coffin-Manson relation or from real strain test data), correct?

Hello, first of all, thanks for the video, was very instructive. There is still something I don't understand with fatigue test : at which speed the force is applied/removed during the test ? The fatigue test is based on a static study (meaning the force is applied very slowly). In the reality, it's not the case and the fatigue test results would be very different if the force is applied in one second or in ten. seconds… So I'm not sure to understand correctly the purpose of such a test ? Wouldn't it be more relevant to create firstly a dynamic study, stipulating at which speed the force is applied/removed and then to create a fatigue study based on the dynamic one ?

Hi there! Your video has been very helpful for my project. However i hve a question to ask. From the static analysis made how does it relate to the fatigue analysis ? I mean.. does the stress come out in static will be used in fatigue ? by importing the data results ?

Hiii I saw yr video it's really useful bt I hve a question what's meaning of cycle(N) like u put and or but what it's indicate day, year, hours, I am waiting for yr response

How can I make an curve for a material that is not exist in solid works program like bone

[NguyenHuuLinh_]

i have a question. for example that failure due to fatigue is likely to occur after approximately 16, 510 cycles. but i don't know 16, 510 cycles approximate how many hours or days?. thanks alot

Nice video, but are these features included in the student version?

[babubikashgogoi]

How did you make the educated guess to input force value?

[hannahr]

Hi, where did you find the SN curve for stainless steel? thanks

[alexfryproductions]

thanks for the video. how can you define the max and min stress for the fatigue cycle. you only input the mean stress?

[hughmungus]

uhhh You kinda already had the study there, I cant follow that, why didnt you start from scratch like someone normally would? This is just a static study?
