AMS classification: 35K55 35Q55 35Q74 %K Magnetostriction %K weak solutions %K thin plates %Z Mathematics [math]/Analysis of PDEs [math.AP]Conference papers %X We consider a three-dimensional model of ferromagnetic material with magnetostriction, coupling the Landau-Lifschitz-Gilbert equation and the elasticity wave equation, with mixed boundary condition. We establish the existence of global in time weak solutions. By asymptotic method when the thickness of the sample tends to zero, we obtain and justify a new two-dimensional model for thin plates of ferromoagnetic magnetostrictive material. %G English %2 https://univ-pau.hal.science/hal-04037816/document %2 https://univ-pau.hal.science/hal-04037816/file/main.pdf %L hal-04037816 %U https://univ-pau.hal.science/hal-04037816 %~ CNRS %~ UNIV-PAU %~ LMA-PAU %~ INSMI %~ TDS-MACS %~ ANR %~ UPPA-OA
