Power Losses in Magnetic Laminations with Hysteresis: Finite Element Modeling and Experimental Validation

Electromagnetic Waves in Media with Ferromagnetic Losses

The operation of a wide variety of applications in today’s modern society are heavily dependent on the magnetic properties of ferromagnetic materials and their interaction with electromagnetic fields. The understanding of these interactions and the associated loss mechanisms is therefore crucial for the improvement and future development of such applications. This thesis is concerned with elect...

Evaluation of Thermo-mechanical stress in work rolls of ring rolling mill under thermal and mechanical loading

The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...

Mechanical Modeling of Initiation of Localized Yielding Under Plane Stress Conditions in Rigid-Rigid Polymer Alloys

Two-dimensional Finite Element Method simulations, which involve consideration of the nonlinearity of a material, have been conducted to gain understanding about the rigid-rigid polymer toughening concept we proposed. The simulation results for the plane stress condition indicate that as long as the inclusion phase possesses i) a 60% difference in the tangent modulus from that of the matrix at ...
