A theoretical analysis for the quasi-static axial crushing of top-hat and double-hat thin-walled sections

Comparison of the energy absorption capability of crash boxes assembled by spot-weld and continuous joining techniques

“…[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The progressive folding of such structures, produced by axial loads, is a very efficient collapse mode: an example is shown in Fig.…”

Static and dynamic axial crushing of spot-welded thin-walled composite steel–CFRP square tubes

“…[1][2][3][4][5][6], and in Refs. [7][8][9][10][11][12][13] for spot-welded hat-section SHS. A significant difference between seam-welded and spot-welded SHS is that the latter are susceptible to fracture of the spot-welds and/or parent material around the spot-weld.…”

Experimental and numerical study on crashworthiness of cold-formed dimpled steel columns

“…Some studies focused on thin-walled columns with innovative cross-sections [5][6][7][8][9][10][11][12][13][14][15]. By contrast, some studies focused on columns made of high strength materials [16][17][18][19], or filled by different materials [20][21][22].…”

“…It was claimed that the simulation errors were smaller than 4.40% and 8.40% in terms of mean crushing force and peak force, respectively [12]. White et al [13] theoretically analysed the effect of top-hat and double-hat section columns' geometric parameters on the crush response. Ly et al [14] then extended the research by using the finite element method and optimized the geometrical parameters of top-hat structures.…”
