This work is about the improved characterization of soft magnetic sheet materials including the evaluation of electromagnetic material parameters and iron loss models under mechanical stress. The focus is on the design and the optimization of the test setup for impressing mechanical stress conditions like tensile, compressive, and shear stresses, to soft magnetic sheet materials for two-dimensional electromagnetic measurements. The specimen?s shape and test setup were optimized concerning a homogeneous mechanical stress distribution and are presented in this paper. The finite element simulation results show that the proposed concept of the test setup raises confidence in measurement results. Finally, soft magnetic material properties are determined under different mechanical load conditions and the results are presented and discussed.
