Handling Stress and Plastics
Handling Stress and Plastics
(OP)
Hi,
I typically design tanks or vessels in aluminum or stainless steel. However, this design has to incorporate a clear window in the side for viewing. I’m thinking about using Lexan or polycarbonate but I don’t know how to calculate the allowable stress value for plastics. The window is 12” diameter and the internal tank pressure will only be 1 psi.
Any help would be appreciated.
Thank you in advance

No there is not any head pressure. The aluminum rectangular vessel will be pressurized with 1psi of air only. The only safetly concern I have is plastic blowing out under pressure. I know it is unlikely, but I would like to do the calculations to back it up. I haven't been able to do the calculations yet, but I think 3/8" thick lexan "should" work well.
Thanks
