Passive vibration damping with magnetostrictive composite material

This paper describes evaluation of an autonomous-material system tailored for free-layer vibration damping of structural elements. The magnetostrictive particulate composite (MPC) material described has moderate stiffness and minimal temperature and frequency dependence. The composite is created by curing Terfenol particles {Tb(1-x)Dy(x)Fe(2),0.2 SPIE Smart Structures and Materials + Nondestructive Evaluation and Health Monitoring SS 49 2007-03-18|2007-03-22 SPIE Smart Structures and Materials + Nondestructive Evaluation and Health Monitoring SS07 725046 San Diego, California, United States Active and Passive Smart Structures and Integrated Systems 2007 6525 Damping and Isolation II 9
