Abstract: Provided is a new and improved method for examining the penetration of fragments in ballistic gelatin through the use of state-of-the art computed tomography (CT) equipment and analytical software. The inventive method can be used for fragment penetration testing as a key performance parameter (KPP). Ballistic gel containing multiple fragments are obtained, placed in a container, positioned in a CT chamber, and scanned. The scan is imported into a Volume graphics software program. A surface determination is made, which is used by one or more algorithms to isolate potential fragmentation within the gel block. The number of fragments, depth of penetration, and fragment mass are then calculated.

Abstract: Provided is a frangible munitions device optimized for a dome and cylinder that yields fragments having shapes corresponding to a predetermined embossment pattern upon explosive rupture. The embossment pattern includes a first set of inner regular hexagonal embossments formed into the dome and cylinder that are aligned with the axis of the cylinder, and a second set of outer pre-deformed hexagonal shapes that distort to produce regular hexagonal shapes after drawing into the cylinder wall. The second set of shapes are separated by sharp transition regions. The shapes are embossed in a repeated pattern around the hollow cylinder and the dome top. The dome yields a plurality of fragments having shapes corresponding to the first set of inner regular hexagonal embossments upon explosive rupture, while the cylinder yields a plurality of fragments having shapes corresponding to the second set of outer pre-deformed hexagonal embossments upon explosive rupture.

Abstract: A drill bit in conjunction with a hammer-drill to penetrate composite metal and non-metal structure or structures including, for example, thick metal or rebar encountered during concrete, rock or masonry boring operations without requiring a change in drill equipment.

Abstract: The present invention relates to using at least one explosive device to enable rapid and accurate positioning and repositioning of at least one explosive charge for controlled penetration of targets. A penetrator allows effective demolition with minimal explosive load. An attachment collar with magnetic inserts allows quick repositioning of explosive devices. A plurality of explosive devices allows a demolition profile to be rapidly created and adjusted on-site to adapt to changes in structural or environmental conditions.

Abstract: Exemplary apparatus, systems, and methods to provide an ability to quickly and securely hand emplace stand-off demolition charges to various surfaces or structures including surfaces including any flat surface. An aspect of the embodiment of the invention is a lightweight attachment bracket that will hold charges at distances up to (e.g., ten inches) away from a vertical target. The bracket is collapsible, therefore provides a user adjustable stand-off, which is necessary for some applications. Attachment to ferrous material can be instant through a set of rare earth metals imbedded in the base of the bracket. A skirt of high strength textile material provides attachment to other surfaces via integrated hooks and rings. Alternative embodiments of the invention could include an electromagnetic system provided to couple the bracket with a battery in order to provide a limited amount of power to operate the system.

Various embodiments of the enclosure or structures are formed with various case hardening or embrittlement processes to increase embrittlement or hardness of the enclosure or structure so as to create a structure or enclosure which has a desired fragmentation capacity while still maintaining sufficient material properties to permit snap-fit insertion of one section into another section and withstand substantial impacts. Embodiments also provide an interlocking structure that minimizes differences in fragmentation or fracturing capacity as contrasted with other portions of the structure or enclosure. An embodiment of the invention includes an enclosure where one section of the enclosure or structure has a first thickness and the second section has a second thickness, wherein the first and second thicknesses are different.
