Abstract
A concept of monitoring the degree of degradation in the multilayered structure of polymer composite package has been developed at the laboratory for modeling damage and failure of machines at Mechanical Engineering Research Institute, RAS. The concept is intended for real-time acousticemission testing of products and employs new criterion parameters that reflect the percentage of location pulses in energy clusters characterizing the processes of destruction of material structure at the micro-, meso-, and macro-scale levels. The developed procedure, algorithm, and software for monitoring the process of degradation in the multilayered structure of polymer composite material package and predicting the residual strength of the product have been successfully tried in static tensile bench tests with a structurally similar sample of aircraft panel containing a honeycomb polymer filler.
