This is a good starting video on the shaft fatigue for beginners. I hope that the students also read the ansys manual and other fatigue books because fatigue FEA is a specialized topic. Common mistakes for beginners are using Von-mises stresses for non zero mean stresses and using mean SN curves (50%) for analysis.
Thank you for your positive feedback on our introductory video on shaft fatigue! You're absolutely right-shaft fatigue analysis is a specialized topic that requires a strong foundation. It's our aim to provide a solid starting point while also encouraging further exploration and learning in this fascinating field.
what do you mean by (using Von-mises stresses for non zero mean stresses and using mean SN curves (50%) for analysis is a mistake!), what is the right choise if i use Soderberg criteria for analysis?
Nice tutorial for fatigue stress analysis, but you need to determine the maximum stress with a stress convergence study in order to find the minimum safety factor.
Thank you for your suggestion! You're right, determining the maximum stress through a stress convergence study is essential for a reliable fatigue stress analysis. By gradually refining the mesh or discretization of the model, the study ensures accurate stress values in complex areas. This allows for a precise calculation of the minimum safety factor, which represents the margin of safety against fatigue failure. Incorporating a stress convergence study enhances the analysis and understanding of structural performance under fatigue loading.
For predefined materials, the SN curve is already available in ANSYS. For custom materials, the SN curve needs to be defined in the material information.
Certainly! Importing data from a vehicle dynamics test rig to ANSYS for fatigue analysis is feasible. ANSYS supports various file formats for importing external data, including CSV, Excel, and other standard formats. Make sure your data is properly formatted and compatible with ANSYS.

Thank you so much...🎉❤
Welcome!!
Hello, can we import data from vehicle dynamics test rig to ansys for fatigue analysis
Yes, you can import data from a vehicle dynamics test rig into ANSYS for fatigue analysis.
thank you so much
Welcome 😊
Can you please suggest some institutions or vendor for analysis. I need refrence
What kind of analysis do you need to carry out?

where do i get S-N curve for fatigue analysis? when i clicked "solve" it asking for S-N Curve
For predefined materials, the SN curve is already available in ANSYS. For custom materials, the SN curve needs to be defined in the material information.
Hello, how much is the diameter please
