Abstract: A functionally graded structure for a protective device includes a plurality of lattice structures including at least a first lattice structure having a first geometry and a second lattice structure having a second geometry. The first lattice structure with the first geometry has a first compression response property and the second lattice structure with the second geometry has a second compression response property that is different from the first compression response property.
