The stresses you'll need to consider all depend on what you're designing and what its intended use will be. I'm not wholly sure that this is the forum for such a question though.
As Jeff Mentioned, the question is very unclear, No worries though. It would give a better clarity if you could give information on the loading scenario. I feel that this discussion could have been posted in the Simulation forum. There could have been many responses for the same.
Have a great day ahead!!
