Abstract
A breaching apparatus includes an impactor element and a self-contained energy source. The self-contained energy source enables the impactor element to impact a first surface of a structure. The impactor element is configured to transmit a localized shock wave through the structure upon impact. The self-contained energy source is capable of accelerating the impactor element to a velocity sufficient to induce spalling at a second surface of the structure. Multiple breaching apparatuses can be supported by a frame to facilitate simultaneous or successive breaching of the structure. The breaching apparatus can be used in a method to breach a concrete structure.
