The contact problem of a circular rigid punch on piezomagnetic materials

In this project, a general theory for the axisymmetric indentation of piezomagnetic solids by a flat rigid punch is presented within the context of fully coupled linear model, in the absence of friction or adhesion. It is shown tha-t the coupling has a significant effect on the indentation force and the magnetic flux through the contact area. In addition, an experiment on the material Terfenol-D was carried out to confirm the theoretical results.
