Quasi-static axial compression of thin-walled tubes with different cross-sectional shapes

Recently more attention has been paid to the energy absorption capability of novel structures in the retrofit of impact or blast protection structure. As the most versatile components, thin-walled metal tubes with different cross-sections are used and specifically explored by many researchers. One method for improving crashworthiness performance under quasi-static axial crushing is to vary the cross-sectional shape with only convex polygons. As...
