Abstract
AbstractIn this contribution we present a variational framework which is suitable for the finite element implementation of energy‐relaxation based magnetostriction models. Our recent work [1] has shown that energy‐relaxation based models are able to capture all key response characteristics of multi‐ferroic magnetic shape memory alloys (MSMA). In order to simulate the response behavior of arbitrarily shaped samples we are switching to a micromagnetically inspired finite element framework [3], where the magnetization inside the magnetic material and the nonlocal demagnetization field are spatially resolved. First results compare the magnetization responses for FE‐simulations and calculations using the demagnetization tensor concept. (© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
