Symposium Structural Metamaterials
Presentation Title Interpenetrating Chain Lattices with Tailorable Energy Absorption in Tension
Author(s) Spencer V. Taylor, Zachary C. Cordero
On-Site Speaker (Planned) Spencer V. Taylor
Abstract Scope This talk introduces the chain lattice, a hierarchical cellular solid comprising two interpenetrating lattices. One lattice toughens the material and prevents catastrophic localized failure, while the other serves as a porous matrix that densifies to absorb energy during tensile loading. An experimentally validated micromechanics model is developed to predict the effect of chain lattice geometry on strength and energy absorption. Our results demonstrate how chain lattices can transform brittle 3D-printable materials into damage-tolerant, notch-insensitive metamaterials.
