>pressure vessels as cylinders for even distribution of of the pressure forces across it. Ideally you want to have it capped off with two hemispheres
The pressures may be equal, but the stress (what I assume you mean by pressure forces) is what matters. The hoop stress is double the longitudinal stress (which is why pressure vessels almost always tend to fail by splitting along the longitudinal axis, despite both the longitudinal and radial axis' experiencing the same pressure). That would make me think the stress at the ends isn't as much of an issue, but I guess funky designs can act as stress concentrations.
