A comparative study on energy absorption of flat sides and corner elements in CFRP square tube under axial compression

The cross-sectional configuration is one of the factors influencing the energy absorption performance of composite tubes under axial compression. Flat sides and corners are basic elements for the configuration. However, their contributions to the energy absorption have not been systematically compared. This paper presents a “press and cut” approach which allows to investigate the energy absorption of flat side and corner elements in a condition...
