Fracture effects of the affused steel cylinders induced by inside head-on collided of the planar shock-waves

Upon the former researches of the fracture effects of the metal cylinders induced by inside head-on colliding of the sliding detonation waves, the similar effects of the affused steel cylinders induced by inside head-on colliding of the planar shock-waves has been numerically simulated with a explicit finite-element hydrodynamic code(LS-DYNA). The simulated results have confirmed that the fracture effects of steel cylinders induced by inside head-on colliding of the subaqueous shock-waves are similar to that of the sliding detonation-waves. The colliding history of the shock-waves and prominence phenomena within the collided section has been reappeared. These results have provided a fundamental method to design the explosive consolidation assembly of W-Cu functionally graded materials (FGMs). The bidirectional affused explosive consolidation assemblies have behaved a good antidetonation quality, which ensures that the safely recovery of consolidated samples.
