    12L14 fatigue properties

    Hi all, Can anyone direct me to a source with a S-N curve for 12L14. I understand the additions of lead and sulfur to increase machineability tend to reduce fatigue properties. I can't seem to find any data that shows this. Thanks in advance!

    FEA static stress for fatigue calc VS. hand calc

    All, I am trying to determine the fatigue life of a shaft (with splines machined into it) in combined rotating and bending. Assuming high cycle fatigue. According to FEA, the max von mises stress is 55 ksi at the fillet between the splines. This agrees fairly well with hand calculations...

    Cosmos works 5.0 shell assembly

    Hi, Im trying to run a static fea analysis on a bicycle frame using shells as the tubing which is quite thinwall (0.4mm-0.9mm). Cosmos apparently cant mesh multiple shells (ie the tubes in the frame) in an assembly,it can only shell mesh individual parts. It can only mesh solids elements in...
