Abstract As a new kind of multi-functional lightweight material, spherical shell cell structure has a great application prospect in aerospace, transportation and other fields. In this work, the mechanical properties of simple cubic through-hole spherical shell cell structure under compression were studied by means of experiment and numerical simulation. The nominal stress-strain curves were obtained, and the rules of effective elastic modulus, yield limit, platform stress, specific energy absorption and other properties with the change of shell wall thickness and spherical center distance was studied. The results showed that some spherical shell cell structures appeared buckling and turn over to form plastic hinges during the compression process, thus enhancing the bearing capacity of the structure. The effective elastic modulus and yield limit of the spherical shell cell structure increased first and then decreased with the increase of the spherical center distance, and the platform stress and specific energy absorption increased with the increase of the spherical center distance. It can be concluded that the spherical center distance greater than or equal to 18.0 mm is a more ideal structure.

Key words： spherical shell cell structure compressive experiment numerical simulation effective elastic modulus specific energy absorption
