  In this study, numerical investigation of energy absorption of cylindrical grooved tubes under dynamic axial load by LS DYNA was considered. In order to achieve axisymmetric collapse mode inner and outer grooves were created around the surface of cylindrical tubes. The purpose of this study was consideration of the effects of number of grooves on energy absorption and crush force efficiency. The results indicate that with the increase in number of grooves the collapse modes would not change. In addition to this, with the increase in number of grooves maximum crush load and collapse modes decrease but the force-displacement curves would be smoother. The results of this study can be used in automobile, railway and aerospace industries. Manuscript profile
