Methods and apparatus are provided for a device that attenuates shock loads experienced by a body supported by a moveable structure during a high energy impact event. The device includes an elongated metal bar with a principal axis coinciding with a length dimension of the bar, and an anti-rotation member configured to rotationally fix the metal bar at a first torque application point to one of the body and the moveable structure. A torque application member is located at a second torque application point on the bar, and spaced apart from the anti-rotation member by a distance defining a working section of the bar. The torque application member is connected to the other one of the body and the moveable structure, and configured to impart a twisting moment to the working section of the bar proportional to an acceleration induced inertia load between the structure and the body.
