Abstract
AbstractThe interaction of detonation waves was widely used in warhead design due to its ability to generate local high‐pressure regions. In this paper, the detonation interaction was investigated by experiments and finite element (FE) models. Experiments were conducted first to capture the fundamental dynamic fracture and fragmentation patterns and they served as a basis of validation for both the FE and analytical models. According to fracture surface, shear fracture is prior mechanism for steel‐plate fragmentation. The FE results indicated the dynamic fracture of steel plate was referred to the pressure difference between the collision area and its adjacent areas. A theoretical analysis of detonation wave interaction in explosive was carried out, and the relationship between the pressure at the collision area and adjacent areas was obtained. In the discussion part, the influencing factors and the optimal results for the plate fracture in the simulation calculation were carried out.
