Effect of compressive stress on hysteresis loss of Terfenol-D
2003
Changes in hysteresis loss of Terfenol-D rods due to compressive stress have been investigated to clarify its characteristics. The hysteresis loss monotonically increases owing to compressive stress, and its increment is in proportional to mechanical work of magnetostriction under compressive stress. The proportionality ratio between them relates to the increment of non-180° walls due to compressive stress in magnetization process.
