Beschreibungen/Notizen

• Acoustic emission diagnostics is applied to three zones of structural transformation in the wingbox: two are at the boundaries of the zone of stringer peeling; and the third is close to the edge of the technological window. Using the proposed methodology for dynamic monitoring of the variation in the contribution of the acoustic emission pulses to the lower, middle, and upper energy clusters, the kinetics of micro-, meso-, and macroscopic damage may be monitored during the loading of the wingbox, and the structural stability of the material in the region of the acoustic emission sources may be assessed.
