Smart Material Applications Piezoelectrics - Tunable lenses, nanopositioning Shape Memory Alloys - Shape modification Magnetostrictives - High force transduction II. Modeling Hierarchies Develop energy relations at lattice level for single crystal, homogeneous compounds. Incorporate polycrystallinity and material nonhomogeneities through stochastic homogenization to obtain macroscopic constitutive relations. III. Experimental Validation PZT5A - Major and biased minor loops Terfenol-D - Major and biased minor loops SMA Thin lm Goal Develop a unified framework for model and control design for ferroic ferromagnetic, ferroelectric and ferroelastic materials.
