Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I've got a pressure vessel that is just an aluminum cylinder with flat caps welded to the ends. Currently, I doing some FEA to properly size those flat caps for a certain factor of safety. Since the pressure in the tank will cause a uniformly distributed load on the wetted surface of the cap, I understand I'm dealing with bending stresses. My plan was to calculate the Von Mises Stress and compare it to the bending strength (or flexural strength), but I can't seem to find that strength property for aluminum 6061 anywhere!

Is there a reason this isn't a well documented material property? Or, if I've gone down a wrong path here, can someone help guide me back onto the right one?

Any help is appreciated!
