Hi
I'm trying to find the best way to calculate the radial expansion of the pressure vessel with a variable length. Please take a look at the image I've for better explanation of my issue.
I have three test cells that have the same dimensions with only length different. Identical internal pressure is applied to all of them. FEA shows that two fist ones have around the same radial expansion (0,0012mm) but the short one with 25mm length expanded 0,0007mm. I found these two equations which give me a Longitudinal Strain and Diametral Strain. But those formulas do not have a length of the pressure vessel as a variable. Calculating Diametral Strain using the formula below I get the same results 0.0012mm shown in two upper FEAs.
The question is how to find the radial expansion of a pressure vessel with a particular length?
