I am working on a design for an odd shaped rotomolded polyethylene tank that will be filled with about 5,000 lbs of sand. I am familiar with designing tanks for liquid storage and low pressure pressure applications. However, I am not sure how to work with sand since is has more shear viscosity...
I want to perform a simulation of an air compartment (rotomolded plastic float tank) as it is pushed underwater to 75% of its buoyant capacity. The pressure on the inside stays the same, but the pressure on the outside changes as water depth increases. The submersion depth is only about 30"...
I currenly design a lot of weldments using square tubing and fabricated brackets. I would like to create some molded shapes to simplify the fabrication process. I know that welding cast iron is not feasable, but can you weld cast steel easily??
I am thinking of a similar material situation...
