Abstract
ABSTRACTAn energy-based constitutive model that can simulate the performance of magnetostrictive actuators and sensors along any of the crystallographic orientations was developed. This model was validated by comparing its predictions with experimental actuator characteristics (λ-H and B-H curves) along the <100> and <110> directions as well as sensor characteristics (B-σ curves) along the <100> direction of single crystal FeGa samples with ∼18-19 at. % Ga. These experimental characteristics were obtained using 6.35 mm (1/4 inch) diameter and 25.4 mm (1 inch) long, oriented single crystal rods grown using the Bridgman method by the DOE Ames Lab.
