CONSTITUTIVE MODELING OF MAGNETO-THERMO-MECHANICAL RESPONSE OF FIELD-INDUCED PHASE TRANSFORMATIONS IN NiMnCoIn MAGNETIC SHAPE MEMORY ALLOYS Conference Paper uri icon

abstract

  • In this work we model the magnetic field induced phase transformation (FIPT) of magnetic shape memory alloys (MSMAs). The working principle of such materials is described by the cross coupling of mechanical, thermal and magnetic fields. The Thermo-magneto-mechanical constitutive equations are derived in a thermodynamic consistent way. A 3-D stress-fieldtemperature phase diagram is constructed using the model. The model is calibrated from the experimental data and the model predictions are compared with experimental results. Copyright © 2010 by ASME.
