Mathematical modeling of elastic waves radiation during screw dislocation segment oscillations

In this paper, we consider elastic waves radiation (acoustic emission) during oscillations of screw dislocation segment under action of external influences. The dislocation oscillations braking by medium was not taken into account. Elements of generalized susceptibility inverse matrix for the screw dislocation segment in nondissipative crystal are written. The energy emitted by the dislocation oscillator has been found. Using numerical calculations of the generalized susceptibility matrix elements for the screw dislocation segment, estimate of the radiated energy is obtained. (paper)
