THE COUPLED SOLUTION OF A RIGID LINE INCLUSION AND A CRACK IN ANISOTROPIC PIEZOELECTRIC SOLIDS

The Stroh formalism in anisotropic elasticity is used to analyze the coupledelastic and electric fields for an iufinite , anisotropic electroelastic medium with a rigid lineinclusion and a crack,The explicit real-form solution on the boundary of the inclusion andmatrlx is given and the classical type of singularity for the elastic and electric fieldcomp onents in the neighborhood of the crack tip is also obtained。
