摘要

An accurate model description of the effects of stress on magnetic properties of materials has become increasingly important in situations where the performance characteristics of magnetic materials, such as magnetostrictive sensors or actuators, can be described and if the theoretical model is physically sound, properties and performance outside of a known range of conditions can also be successfully predicted.;This work reports on the recent investigation on the stress dependent hysteresis and magnetomechanical effects of ferromagnetic materials. The magnetic properties of several materials, such as nickel, both cold-worked and annealed, and steel, under various stresses were measured and modeled using an improved model theory.;By investigating the previous model theories, this work gave a new way to modify the existing and currently used models for describing the effects of applied stresses on magnetization of materials.
