Abstract

We report cyclic strain measurements form an experimental Terfenol-D actuated polymer matrix composite. Basic material constitutive response are identified as functions of frequency. Anhysteric theory is used to quantitatively model the behavior of the composite. Insight provided by the analysis is used to suggest material design changes leading to improved composite performance.
