A novel theoretical framework for analysis of indentation of magnetostrictives, based upon a linear material response model, is developed. The governing set of partial differential equations is solved for the case of an incompressible material, resulting in a solution which predicts the relationship between the change in magnetic flux and the applied load near the area of contact between the indenter and the specimen. This relationship (referred to as a <D-P curve) and the relationship between the applied load and the indenter displacement (a P-h curve) together give a "signature " of the magnetostrictive response of a given material. Quantitatively, the flux change is predicted to be very small. A preliminary design concept of an experimental apparatus for the instrumented indentation of magnetostrictive materials is presented. This design allows for the simultaneous measurement of load, displacement, and magnetic flux. These measurements, in conjunction with the theoretical framework, provide a new method for the characterization of magnetostrictive materials in bulk and thin-film form
