This contribution details buckling tests and numerical results for shallow spherical caps subjected to static and uniform external pressure. Six mild steel caps were carefully CNC-machined from a solid billet. Three caps were designed to fail elastically with the remaining three failing within the plastic range. Caps’ shallowness parameter, , varied from 3.5 to 5.5, and radius-to-thickness ratio varied from 300 to 1800.
