  • Energy dissipating damper
    Patent number: 11473431
    Abstract: An energy dissipating damper includes a first end portion configured to be coupled to a first structure, a second end portion, opposite the first end portion, configured to contact a second structure, and a body portion extending from the first end portion to the second end portion. The body portion includes a plurality leaves. The plurality of leaves may be fixed together at the first end portion and may be separable from each other at the second end portion. In response to the energy dissipating damper being in a loaded state, the plurality of leaves may be in direct contact with each at the second end portion. The energy dissipating damper may further include a contact element coupled to the second end portion, and the contact element may comprise an abradable material.
