Presentation: Characterization and modelling of silicon-steel under multi-axial magnetic and mechanical loading
In this presentation, we expose different aspects related to the characterization and modelling of Silicon-Steel. Indeed, the Silicon-Steel is one of the most used materials for the construction of the magnetic core of electrical machines and transformers, among others. The design and analysis of these devices require deep knowledge of the magnetic and mechanical properties of the material as well as adequate models to be incorporated in the analysis software, e.g., finite element simulation programs. The main interests of the presentation are the vector-properties characterization and modelling as well as the magneto-mechanical coupling in the material. Furthermore, issues such as the effect of plastic deformation and residual stress on the permeability and losses in the material are very important to characterize and model. We will present the developed characterization setups and models as well as some challenges related to the incorporation of these models in the finite element simulations of electrical machines and the validation of these models through experimental setups. The experimental work, besides giving important input for the simulations, can also help gaining better understanding of the underlaying physical phenomena, which might help developing better materials as well.
