In this study, the compressive response especially average load P_ave of lattice-cored sandwich tubes has been studied using the nonlinear finite element method. Numerical analyses are undrtaken based on the tubes associated with a variety of micro-architecture of the lattice core. This study shows that lattice sandwich tube has a potential to control the non-axisymmetric deformation of the tube to the axisymmetric deformation and enhance the average load P_ave.
