    Ansys Fatigue Analysis Help needed

    I want to perform fatigue analysis on a part made of 17-4ph. I only found the S-N curve for the fatigue test of the notched specimen. I couldn't find test results of the un-notched specimen. How can I use data of the notched specimen fatigue test in Ansys? I believe, notched test data are for...

    Can anyone suggests a good reliable source for fatigue life of 17-4ph H1025?

    I am trying to find an S-N curve and/or the strain-life curve of 17-4ph h1025. I found the data for high temperatures on the AMS website but nothing at room temperature. That is strange, I believe if it is tested at high temperature than there should be some reports available for room...

    Stress analysis of threaded pipe joing due to internal pressure?

    I want to do a stress analysis of an adapter that is designed to convert Metric thread to US standard. That converter has both female threads. I want to know how to confirm stresses at the joint with minimum computation. The pipe system is at high pressure and room temperature. It will transfer...
