TLDR
In this article, a measurement study was conducted to investigate how changes in temperature, dynamic strain amplitude, and magnetic field strength influence the behavior of a magnetosensitive material, and the results indicated that the temperature is the most influential of the parameters as the material stiffens significantly when the temperature reaches the transition phase.Abstract:
A measurement study is conducted to investigate how changes in temperature, dynamic strain amplitude, and magnetic field strength influence the behavior of a magnetosensitive material. During the measurements seven temperatures, four magnetic fields, and three dynamic strain amplitudes are used over a 200 to 800 Hz frequency range. The results indicate a decrease in shear modulus magnitude as the dynamic strain amplitude is increased. As the frequency and magnetic field strength increases the magnitude increases. However, the measurements indicate that the temperature is the most influential of the parameters as the material stiffens significantly when the temperature reaches the transition phase. Understanding the temperature dependence increases the knowledge of magnetosensitive materials.read more

A model of the behaviour of magnetorheological materials
TL;DR: In this paper, a quasi-static, one-dimensional model is developed that examines the mechanical and magnetic properties of magnetorheological materials, and the model attempts to account for magnetic nonlinearities and saturation by establishing a mechanism by which magnetic flux density is distributed within the composite material.

Model of magnetorheological elastomers
