Abstract
An opening crack model is proposed by considering the effects of various physical properties inside a crack of thermomagnetoelectroelastic solids in the present article. The thermal flux, electric displacement, and magnetic induction at the crack surfaces are assumed to be dependent on crack opening displacement. Applying the Fourier transform technique, the thermal stress intensity factor for an opening Griffith crack in thermomagnetoelectroelastic solids is given in the explicit form. The effects of applied magnetoelectromechanical loadings and the physical properties of crack interior on the normalized 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 magnetoelectromechanical loadings and various physical properties of crack interior for a crack filled with a medium.
