Analytical formulation and numerical modelling for multi-shell toroidal pressure vessels

•A novel shell-assembly of toroidal form for fluid containment is proposed.•A formulation is presented for determining the state of stress in the loaded vessel.•An approximate buckling solution is formulated for the middle regions of the toroid. Depending on the required solution, this paper present...
