| Abstract Scope |
Interlocking metasurfaces (ILMs) are a new class of mechanical metamaterials offering a robust, nonpermanent joining technology. ILMs are built as architected arrays of interlocking unit cells that deliver adhesive-like properties to otherwise non-adhesive surfaces. Strategic designing of these unit cells offers explicit control over the engagement and disengagement forces of the ILM. This work attempts to produce optimally robust ILMs through parametric- and evolutionary-based optimization of the unit cell designs. When computationally and experimentally tested, the resulting designs prove to be considerably stronger in tension and shear compared to intuitively derived designs. These results offer insight into how ILMs can be more strategically designed for improved performance. The presented design and optimization framework ensures ILMs can offer a robust joining technology in a host of applications ranging from lattice connection to dissimilar material joining.
