| Abstract: | The Mushroom tests used to study the corner turning of explosives,PBX-9404 and PBX-9502,were modeled by using the finite element hydrodynamic code LS-DYNA.The calculated results reveal that under the same test conditions,detonation breakout angle in PBX-9502 is smaller than that in PBX-9404,and there are obvious dead zones in PBX-9502,showing PBX-9404 has better detonation diffraction than PBX-9502.The change of diameter of booster and half-scale hemisphere explosive has a little influence in some parameters used to characterize the corner turning of explosives. |
