Lattice structure materials are commonly used for reduction of mass while maintaining desirable mechanical properties and to modify mechanical behavior of a given base material. They have applications within aerospace, biomedical, automotive, and other engineering fields. The mechanics of bending dominated lattice structured materials is dominated by beam bending which allows for significant mechanical compliance. Super-elastic shape memory alloys are able to accommodate large amounts of recoverable strain when loaded. Super-elastic shape memory alloy bending dominated lattice structured materials could allow for significant kinetic energy absorption dissipation. Presented are finite element models of super-elastic shape memory alloy lattice structured materials optimized by varying the geometry to maximize energy absorption and dissipation.
