| Abstract Scope |
Interlocking metasurfaces (ILMs) are a new type of joining technology that aim to overcome challenges inherent to conventional joining technologies. These structural metamaterials feature consist of autogenous latching mechanisms similar to those found in nature such as bush cricket feet. The mechanical performance of ILMs is controlled by a combination of material, unit cell topology and unit cell interactions, making their design a complex challenge, particularly in extreme mechanical and thermal environments. Due to the difficulties in simulating these conditions, experimental work is essential to evaluate the performance of these metamaterials and ensure effective designs. We will present recent findings on the vibration, shock, and thermal performance of ILMs, highlighting how the combination of material, unit cell topology and unit cell interaction enhances the performance of these joints, resulting in significant improvements over conventional joining technologies. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
