- Mechanical metamaterials offer a paradigm shift in materials design, as the microstructure-property relationship no longer exclusively dictates the material properties. However, promising metamaterial architecture such as the re-entrant ones still possess strain instability preventing their scalability to industrial application. This research is the first to demonstrate how the stability of auxetic metamaterials with a negative Poisson’s ratio can be improved. The approach allows the utilisation of unexplored regions in the material property space, including ultrahigh strength‐to‐density ratios. The research solves one of the fundamental issues to scale metamaterials for real-world products such as lightweight energy absorbers.
