Abstract
Methods and apparatus are provided for a shock attenuation device configured for use in conjunction with a body movably mounted to a structure along a stroking direction to attenuate shock loads associated with a high energy impact event on the structure. The device includes an elongated metal frame with left and right sides symmetrically disposed about a longitudinal slot extending from proximate a first end of the frame to a second end. The frame is mountable to one of the body and structure in an orientation causing the longitudinal slot to align with the stroking direction. A mandrel mountable to the other one of the body and structure is positioned in the frame at one end of the slot. The mandrel has width and length dimensions measured in the plane of the frame, wherein a maximum width of the mandrel is greater than a width of the slot.
