Abstract: A nonlinear mechanical element including a buckling column and hard stops. In one embodiment when the nonlinear mechanical element is subjected to an increasing compressive load, the buckling column buckles at a critical load, resulting in reduced stiffness past the critical load. One or more lateral hard stops may be provided adjacent to the buckling column to prevent the buckling deformation from exceeding a certain extent, and axial hard stops may be provided to shift the load path away from the buckling column when a certain amount of compressive displacement has been reached.
