Combined stress in weld of rectangular storage tank for dielectric oil

Combined stress in weld of rectangular storage tank for dielectric oil

Hi all,

I'm trying to find the maximum allowable pressure inside a rectangular storage tank filled with dielectric oil. The tank consists of 6 aluminium 6061-T6 plates which are connected with corner joint fillet welds. I assume that the welds will fail first, which will determine the maximum allowable pressure.

Which stresses do I add together in order to get the maximum principle stress in the weld? I made a calculation for the shear stresses in the weld using the Huber-Hencky equation and I calculated stresses in the long edges of the side plate and top plate (assuming these plates would be clamped on all edges). I took an internal pressure value of 4.5 bar (0.45 MPa). A sketch of the situation can be found in the attachement.

I am not quite sure how to add these stresses and I may overlook something. Any help would be much appreciated. Thank you in advance!
