Minimal-surface-based multiphase metamaterials with highly variable stiffness

Materials & Design
Variable-stiffness materials have a unique ability to change their stiffness reversibly in response to external stimuli or conditions. However, achieving ultrahigh stiffness change is often constrained by the geometric organization of the microstructures
