Abstract:
This paper introduces Machine-Augmented Composite Materials (MACterials), which are composites embedded with small, simple machines to achieve unique properties not otherwise attainable. The research developed a comprehensive understanding of these materials for infrastructure applications, including manufacturing methods for embedding machines of various sizes within a matrix material. Through experiments and validated analytical and finite-element models, the study demonstrated the ability of Z-shaped machines to convert compressive into shear displacements with varying efficiency based on geometry and explored the design optimization of fluid-filled hourglass-shaped machines for vibration damping, identifying an optimal viscosity for efficient damping.
