文摘

A steel thin-walled circular tube with internal grooves is fabricated through SLM method. The crushing behavior of the printed tube is studied experimentally and numerically. The tube experiences buckling stage and splitting stage during the process. The internal grooves control the initial buckling position and fracture position.
