✦ Synopsis

A moving screw dislocation in a transversely isotropic piezoelectric material is investigated in detail. The analytical expressions for displacement, electric potential, stresses, electric displacements, strains, and electric fields are obtained. When the velocity of the dislocation is zero, or when the piezoelectric constant is zero, the results derived in this paper can reduce to known results.
