In this paper, the energy absorption of steel thin walled hemi-spherical shells are investigated under compression loadings. Loadings are applied to specimens using a rigid flat plate. Also the effects of geometrical parameters of specimens like as diameter and thickness are studied on buckling load. The experimental tests performed using an Instron 8802 servo-hydraulic machine. Result shown that the higher diameter spherical absorbed less load than the one of lesser diameter in same thickness.
