“…The stress induced magnetic field changes in magnetostrictive composite materials have been studied by several research groups (e.g. [4][5][6][7][8][9][10][11][12][13][14]). In particular, Yoffe et al [11] presented a model for the magneto-mechanical response of magnetostrictive composite materials that is based on an assumed sequence of physical processes that occur during the sample preparation and testing (see section 2).…”

“…In section 4.2, we present magneto-mechanical measurements to reveal the effects of the strain rate, reversibility and hysteresis in the magneto-mechanical response of magnetostrictive composite samples subjected to uniaxial compression. Unlike all previous experimental studies [9,11,12], which have reported only magnetic field versus stress curves, we present simultaneous measurements of the stress, strain, and induced magnetic field. These tests provide much more comprehensive data that is essential for evaluation of stress/ strain sensing capabilities.…”

Stress induced magnetic field changes in epoxy-based Terfenol-D composite materials offer a unique way for stress sensing by using a remote magnetic field sensor. The article presents a study of key factors that are crucial to the performance of stress sensors but have not been studied before. These include the sensitivity, reversibility, hysteresis and strain rate effects. Measurements of magnetic hysteresis curves revealed the enormous effect of the 180° domain switching on the amplitude of the magnetic field induced by the sample. Simultaneous measurements of the stress, strain and magnetic field exhibit no recognizable residual strain, high level of reversibility and small amount of hysteresis in the magnetic field versus stress curves. Comparison between calculated and measured curves demonstrated good agreement and strengthened the model assumptions. The results of this study indicate on the suitability of magnetostrictive composites for stress sensing applications.

This chapter presents the methodology of designing and testing wideband actuators and energy harvesters which can be treated as one device called a mechanical resonator. In order to obtain described effects, the magnetostriction phenomenon was used. This effect enables the construction of resonators in selected frequency bands, including the ultrasonic range. Cores made of giant magnetostrictive materials (GMM) were used for the construction. Considerable attention was given to composite cores to reduce the weight of pure Terfenol-D. The influence of the volume fraction of Terfenol-D powder, the size of its grains, and the direction of polarization on the value of magnetostriction in a wide frequency band were investigated. The magnetostriction of composite cores and solid Terfenol-D samples was also compared. The structure and the use of magnetostrictive cores containing a combination of NdFeB magnets and pure Terfenol-D are also presented. An important issue was also the development of our own methodology of magnetostriction testing, including the use of fiber optic sensors (Fiber Bragg Grating sensors, FBGs), Hall's sensors, and the original measuring system for magnetic field visualization (Magscanner). The chapter also discusses several own designs of actuators and energy harvesters, including shock harvester, resonant harvester, and energy transmission system.

Therefore, an attempt to study the Villari effect in the composites manufactured with the GMM powder was undertaken.…”
