This work investigates energy dissipation in machine augmented composite (MAC) materials consisting of small machines in a matrix. The machines are fluid-filled tubes, and the tube cross-sectional geometry causes fluid flow when deformed. Dimensional analysis identifies the ratio of solid moduli to the product of driving frequency and fluid viscosity as an important parameter. Finite element models predict the performance of the MAC lamina. The highest energy dissipation predicted is 0.8 out of 1.0.
