Abstract Scope |
Interlocking metasurfaces (ILMs) are a new class of mechanical metasurfaces built from architected arrays of interlocking features that can serve as a nonpermanent, robust joining technology. An ILM's strength is governed by the constitutive material, orientation, and topology of its latching unit cells. The presented work optimized the topologies of ILM unit cells to maximize strength in tensile and shear loading using parametric optimization, genetic algorithms, and deep machine learning methods. Experimental validation confirmed that the optimized designs achieved considerable strength increases for isolated unit cells and arrays of interacting unit cells (metasurfaces) compared to a human intuitive design. This study compares how unique design methods can result in high-performing design solutions to maximize ILM effectiveness under single- and multi-objective scenarios. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
