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

<div>Typical failure modes of square tube in Mode II. (a) The square tube is just cracking (<i>a</i> = 4.0 mm, <i>R</i> = 13 cm, <i>m</i> = 100 g + 160 g, TZ33). (b) The crack presents a radial H-type crack (<i>a</i> = 3.0 mm, <i>R</i> = 18 cm, <i>m</i> = 100 g + 160 g, TZ7).</div>
