Viscoelastic interaction between a screw dislocation and a piezoelectric inhomogeneity with an interfacial rigid line

摘要

The problem for the interaction between a screw dislocation and a piezoelectric circular inhomogeneity with one interfacial rigid line in a viscoelastic matrix is investigated in this paper. Based on the elastic-viscoelastic correspondence principle, the analytical stress fields and image force for the problem are presented. The results show that the influences of the viscoelastic properties of the material together with rigid line's length and inhomogeneity's piezoelectricity upon the time-dependent image force are significant. The time-dependent image force evolves toward a constant value as time elapses. Results presented in this paper are in agreement with the previous solution as special cases.
