An opening crack model for thermo-magneto-electro-elastic solids

摘要：

　　In previous studies of fracture analysis for a thermo-magneto-electro-elastic solid,the crack-face thermal boundary condition is always assumed to be fully insulated or conductive.In the present paper,an opening crack model is proposed by considering the various physical properties of crack interior.The thermal flux,electric displacement and magnetic induction at the crack surfaces are assumed to be dependent on the crack opening displacement.The effects of applied magneto-electro-mechanical loadings and the thermal conductivity inside a crack on the thermal stress intensity factor are investigated.The obtained results reveal that the thermal stress intensity factor depends not only on applied thermal loadings but also on applied magneto-electro-mechanical loadings and various physical properties of crack interior.
