We consider the problem in the dynamic theory of elasticity about steady-state oscillations in a massive elastic body that is at the pre-fracture stage of material under antiplane strain. The process of acoustic emission (AE) at the stage of accumulation of defects representing a finite tree graph directed toward the free boundary of the elastic body is investigated. The problem about the radiation of a defect has been solved under the assumption of the activity of its part nearest to the body boundary. A variational approach was used to solve the inverse problem of reconstructing the amplitudes of radiation of the defect based on AE signals.
