TY - JOUR AU - Kang, Kiju AB - Shellular structures comprising three triply periodic minimal surfaces (TPMS), namely P, D, and F-RD surfaces, are evaluated for their resistance to failure resulting from elastic buckling and plastic yielding under hydrostatic pressure through finite element analysis. Critical pressures are empirically expressed as functions of volume fraction (f) and relative thickness for both failure modes. For a given relative shell thickness, the critical pressures of the F-RD shellular structures with f = 0.5 and 0.3 are mostly higher than those of conventional cylindrical pressure vessels. The transition from plastic yielding to elastic buckling is delayed with the decrease in thickness compared to the cylindrical vessel. However, the internal volumes per unit weight of all TPMS shellular structures are considerably lower than those of conventional spherical and cylindrical vessels.
