Shell max von Mises in Nastran

Anonymous · ‎03-29-2021

Hi,

I am currently working on a project where Nastran has earlier been used. I have shell stress results with this in the corner.

Does anyone know where the stresses are retrieved from when SHELL MAX VON MISES -1/2 is the output? Mid-surface?

Thank you.

Hi @Anonymous

"1/2" refers to the top and bottom (or maybe the bottom and top) surface of the shell. The result is showing the larger value from the top or bottom on both side of the element so that you do not need to rotate the model around to look at both sides of the element.

Out of curiosity, what program are you using to display your results? What company made the Nastran are you using? If you are using Autodesk Nastran, what version is it? (You can get the version number from the header of the log or output file.)

If not provided already, be sure to indicate the version of Inventor Nastran you are using!

Hi,

Thank you for the quick answer.

I am actually not sure, this is from an old report which my company did not do. It just states that FEA was done in Nastran.
