A Study on the Evaluation Method for Bending Collapse Behavior of an Aluminum Square Tube

굽힘붕괴를 수반하는 알루미늄 사각관의 시험법에 관한 연구

To evaluate the bending collapse behavior of an aluminum square tube, a finite element simulation for the four-point bending test was suggested. Local buckling deformation near the center of an aluminum tube specimen was induced which has been partly inserted by two steel bars. Simulation results showed good agreements with those of experiment.
