A Homogenization Model for Soft Magnetic Composites Considering the Effect of Mechanical Stress

Soft magnetic composites (SMC) are an alternative to laminated steels for the design of smaller and lighter electromagnetic devices. Such electromagnetic devices might be subjected to significant mechanical stresses that can alter their electromagnetic properties. This article presents a homogenization model that provides estimates for both the nonlinear magnetic response and the eddy current (EC) losses of SMC subjected to a stress state.
