Abstract :
This paper proposes a magnetomechanical 2-D finite-element solver embedding an energy-based material model. The energy-based material model determines the value of the permeability tensor in each material point of the computational grid based on the material data, the magnetic field strength, and the mechanical stress. The simulation results are compared with the measurement data for a nickel I-beam benchmark.
