Damage and fracture mechanism of aluminium alloy thick-walled cylinder under external explosive loading

Characterization of adiabatic shear bands in the zirconium alloy impacted by split Hopkinson pressure bar at a strain rate of 6000s−1

“…In our experimental results, the formation of the TBs bifurcation may be related with the single loading and repeated loading. Under dynamic deformation, the shear band bifurcation has been observed in the single loadings [8,47,48], and the shear band bifurcation formed in the zirconium alloy has been observed in single loading at a strain rate of 3000 s À 1 in our experimental results, indicating that the shear band bifurcation can be induced by single loading. In addition, the repeated loading leads to the stress concentration point or preferential propagated direction changed slightly, then speeds the formation of the shear band bifurcation.…”

The effects of aging treatment and strain rates on damage evolution in AA 6061 aluminum alloy in compression

“…4e and f). Yang et al [29] reported that bifurcation of ASBs occurred in explosively loaded AA 7075 aluminum alloy as a result of barriers such as impurity, defects or particles on the bands' propagation paths, which hinder their propagation along the original paths, and force them to propagate in the directions where the resistance to propagation is low. We did not observe such barriers at the bifurcation points in the AA 6061 alloy.…”

Dynamic deformation behavior of 93W-5.6Ni-1.4Fe heavy alloy prepared by spark plasma sintering

“…The shear band width in the CLS0 specimen after dynamic loading was about 110 μm, and it then decreased with the W grain size in the SP-sintered 93WHAs. Yang et al [29] reported that the propagation of local shear band could absorb more energy and restrict the growth of shear bands in the surrounding area. With a narrower shear band and more amount of shear strain, the energy exhausted in the surrounding area is less than that with wider shear bands.…”
