Evaluating polypropylene tubes

Question asked by Ryan Fisher on Oct 6, 2017

Hello all,

I'd like to find a way to evaluate polypropylene tubes with cutouts like the one pictured. Many variables to consider such as wall thickness, OD, and cutout dimensions and shapes. We modeled this one, ran an evaluation and came up with the image attached. It doesn't tell us much without a yield strength. I'm not certain von mises is the best way to evaluate these. We don't have solidworks plastics or the capability of nonlinear analysis at this time. Is that what I need to be able to take a given tube and get some data to compare against another similar tube?

 

Thanks all
