Hi All,
Im just about to embark on designing some underground cylindrical rainwater tanks roto moulded using Polyethylene. The tanks will be backfilled with pea gravel. I have tried to do as much research as i can on loading of undeground tanks as this is a brand new area for me.
I have...
I have ran a non linear analysis on a plastic rotomoulded tank where the tank is pressurised up to 0.3 bar for 30 mins. The tank is made out of polyethylene which we are assuming has a yield stress of 17 Mpa.
The analysis is telling me that one section of the tank will see a stress of 20 Mpa...

I am about to embark on using FEA (Cosmos works) with Rotational Moulded Products i.e Oil tanks, fuel tanks,large hollow objects made out of Polyethylene. I am only concentrating on linear analysis using long term creep data. Anyone know any useful links/books specific to roto moulding to help...
(I have posted this question 3 times as visitor and no response so i decided to join the bloody thing to try and get an answer)
Currently using solidworks and about to purchase FEA software. I design Roto moulded products using plastic and have been advised to purchase non-linear analysis...
