Estimating the term…
The integration of dissimilar materials poses a significant challenge in engineering, necessitating innovative solutions for robust and reliable joining. Interlocking metasurfaces (ILMs) are a new joining technology comprising arrays of autogenous features patterned across two surfaces that interlock to form robust structural joints. The present invention is directed to optimizing the tensile performance of ILM joints formed between dissimilar materials. Parametric optimization can be used to identify optimal unit cell geometries for maximal yield strength. The invention enables the design of stronger ILM joints between dissimilar materials, thereby making ILMs a versatile and effective joining technology in diverse engineering applications.
Interlocking metasurfaces, comprising a first metasurface of a first material having a first array of mechanically interlocking surface features that mate with a second metasurface of a second material having a second array of mechanically interlocking surface features.
