The influence of the flow stress of the copper liner of a small-caliber high explosive (HE) on the penetration performance is investigated via numerical analyses. A contour map for depth of penetration (DOP) is constructed on the plane defined by the yield strength (A) and degree of work hardening (B) of copper. The influence of the flow stress of the copper liner (described by values of A and B) on DOP is shown to be significant, indicating that the flow stress of the liner cannot be neglected in the process of designing the HE. The flow stress of copper needs to be tailored appropriately so that its A and B combination is located at the maximal DOP position on the map. The DOP map is shown to be very sensitive to the geometry of the HE, which indicates that the liner properties (A and B) should be integrated into the design variables together with the geometric variables in the design optimization process for a high explosive.
