In the present research, axial crushing behaviors of foam-filled holed tube are investigated by performing quasi-static compression tests. The possible deformation modes obtained. experimental results show that energy absorption performance empty can be greatly enhanced filling aluminum foam. Furthermore, a novel theoretical model for concertina mode is proposed based on super folding element method, and validated previous results. interaction between wall foam filler, normalized mean force...
Energy absorption characteristics of polygonal multi-cell tubes with different cross-sectional shapes under quasi-static axial crushing are investigated systematically. Based on the SSFE theory and CE method, theoretical models for predicting mean force proposed, expressions normalized (NFm) special energy (NSEA) derived. Numerical also established using software ABAQUS/Explicit. The results predictions numerical simulations about 36 design conditions in good agreement experimental those...
As an energy absorber, circular tube with wide external circumferential grooves has excellent mechanical properties, and it been defined as 'Type B' grooved tube. In the present work, a novel analytical model of is proposed by considering curvature plastic hinge. addition, fitting equation maximum angular displacement thin-walled section obtained. The theoretical methodology indicated that both total absorption mean crushing force depend on geometric ratios R/h h/t. Based axisymmetric...
Grooved tube has proved to be an effective energy absorber due its excellent controllability during axial crushing. In the present research, a novel named two-stage grooved is proposed. Three approaches are put forward improve material utilisation of by reducing dimensions thick-walled section. addition, enhance stability and absorption performance, aluminium foam filled in empty tube. An analytical model for foam-filled established, which semi-empirical constant reflect tube–foam...
