Why
Existing research has largely focused on passively characterizing fracture in conventional lattice architectures, and the connection of elastic instabilities to fracture resistance remained unexplored.
The Frontline Impact
How this affects you
This work represents a shift from passive observation to active control of fracture mechanics, establishing a new framework for designing metamaterials with tailored fracture resistance. It advances the fundamental understanding of instability-fracture interactions in metamaterials and suggests a broadly applicable route for programming fracture behaviours through instability design.
