Propagation of plane waves of a defect field in a viscoplastic medium in the presence of an interface between two media

The dynamic equations of the continual theory of defects are used to study the structure of the waves of a defect field characterized by a defect density tensor and a defect flux tensor in a viscoplastic medium. Relations are obtained that define the passage of defect field waves through an interface between two media. Particular cases of media with rapidly and slowly decaying waves are considered.
