A warhead includes a body, a patterned liner made of plastic, and an explosive charge disposed within the liner. The liner pattern is formed of gaps and liner elements. The explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements. Upon detonation of the explosive charge and because of the temporal delay in transmitting the detonation energy between these two sets of sections, the warhead body is caused to shear and break into fragments with controlled size. The use of plastic as the liner material also provides a welcome safety feature for this warhead. In the event of unwanted heat ignition, the plastic (which is also low melt temperature material), would melt to seal the explosive and would also flow. Because of the plastic, neither sudden pressure nor heat/ignition inside the round, would therefore be as catastrophic.

What is claimed is: 1. A cylindrical warhead with controlled fragmentation, comprising:a cylindrical liner of plastic material that is formed in a predetermined pattern;a cylindrical body that houses the liner;a cylindrical explosive charge that is disposed within an interior surface of the liner;wherein the liner pattern includes a plurality of gaps and a plurality of liner elements, and wherein the gaps are interposed among the liner elements;wherein the explosive charge includes a first set of sections that are disposed adjacent to the liner gaps and a second set of sections that are disposed adjacent to the liner elements;wherein upon detonation of the explosive charge, the detonation energy of the first set of sections generates a first force that is transferred directly to the interior of the body;wherein upon detonation of the explosive charge, the detonation energy of the second set of sections generates a second force that is transferred to, and dampened by the liner elements, and is transferred therefrom, after a predetermined temporal delay, to the interior of the body; andwherein a temporal delay between the first force and the second force and further wherein the dampening by the liner elements, cause the first set of sections and the second set of sections to create a pattern of localized transitional regions of intense stretching with high gradients of pressures, velocities, strains, strain rates, and yield strengths that are generated on the body in different directions, so as to cause the body to shear and break into fragments with controlled size; andwherein, in the event of unwanted heat or pressures of launch, the liner plastic melts and flows acting to seal the explosive from catastrophic fratricide, and further the melted plastic also flows to exit the warhead to eliminate pressure within the body.
