Abstract：The oblique impact theory of detonation waves at the explosive-metal was applied in design of shaped charge. Relationship between the pressure peak P in the interface of copper and incident angle φ0 was got by using LS-DYNA. The numerical simulation results coincided well with the theoretical calculation results and experimental datum. An engineering method to calculate the proper liner height of tapered and spherical shaped liner was established under the condition of one-point detonation, which was applied in the design of a grouped liner warhead. The calculation and analysis method above supple a design to define liner height, which can enrich the design method of shaped charge warhead.
