Abstract Scope |
Determining the energy absorption capabilities of lattice geometries during shock events is important for the development of impact-resilient structures for a variety of applications including bio-medical and consumer products. Current energy absorption measurement techniques for lattices are performed at constant quasi-static strain rates unrepresentative of real-world environments. A novel instrumentation package was designed and installed on a commercially available drop tower that uses first-principal conservation of energy techniques to determine the amount of energy absorbed in a lattice or solid coupon during an impact event to an unprecedented accuracy. The results provided by the apparatus can be used for Finite Element model validation, rapidly testing performance of additively manufactured materials, and for designing novel impact resilient structures. |
