Energy dissipation is an important material property for materials used inapplications such as armor, airplane wings, and automotive vehicle crumple zones. superelastic Nickel-Titanium (NiTi) and compliant under-dense materials both have excellent energy dissipation properties. Current research suggests that compliant underdense materials made of superelastic NiTi have desirable energy dissipation properties. A rhombic dodecahedron Lattice Structured Material (LSM) is an example of a compliant under-dense Material which has potential to exhibit desirable energy dissipation properties when manufactured from superelastic NiTi. In this work, finite element modeling of a superelastic NiTi rhombic dodecahedron Lattice Structured Material is performed and an optimum for energy dissipation based solely on geometric modification is found.
