Rupture of architected materials

Designed for diverse functionalities and applications, novel structural materials are required to be sustainable and manufactured in a responsible manner. These timely demands are most efficiently addressed through engineered geometry used to control their properties. The field of the architected materials, including mechanical metamaterials, is nascent but growing rapidly. Such materials, in their standalone, bulk form have a very limited applicability - a concern and motivation central to this work. To unlock their potential they need to be designed as integrable subcomponents. Architected materials connectivity and failure will become critical, requiring theoretical, numerical and experimental frameworks- such are not existing. No previous studies have explored adherence and rupture of architected materials and their efficiency in transmitting the load between the solids once being confined - a model example for this project found on multiple occasions in the nature. To seek progress in such promising field, this VILLUM Experiment project will explore relation between the geometry and topology of architected materials and their fracture properties under confinement. The ultimate goal is to design and control architected materials (i) adherence and (ii) rupture, and relish laws enabling optimal design from micro to macro scale mechanics.
