Experimental Investigation on the Deformation and Fracture of Steel Square Tubes under Double-Explosion Loadings

<div>Typical failure modes of square tube in Mode III. (a) The crack presents an axial H-type crack (back without penetration) (<i>a</i> = 3.0 mm, <i>R</i> = 16 cm, <i>m</i> = 100 g + 160 g, TZ9). (b) The crack presents an axial H-type crack (back penetration) (<i>a</i> = 3.0 mm, <i>R</i> = 12 cm, <i>m</i> = 100 g + 160 g, TZ11).</div>
