摘要

Inlays for a shaped charge and corresponding usage methods are provided. An exemplary liner includes a generally conical shape having a tip, an open side, a liner wall that includes a thickness, and an axis that extends through the center of the liner from the tip to the center of the open side. The liner includes a liner height that extends in a vertical plane from the center of the open side to the tip, a liner radius that extends along a horizontal plane perpendicular to the axis on the open side of the liner and that extends from the Axis extends to an outermost edge of the insert wall. The ratio of the liner height to the liner diameter is about 0.90 to about 1.10. The liner wall includes a tip curve, a first wall curve, a second wall curve, and a third wall curve.
