Purpose: In the paper an evolutionary model of fatigue destruction was described. The aim is in as much as possible faithful modeling of processes during constructional materials exploitation observed, particularly progressing of strength ability loss or other useful characteristics changes. Design/methodology/approach: The MES was choosed as a discretisation method. The model evolution goes sequentialy – chaotic system modification by actual state analysis is preceded. Evolution stage and material state characteristics evaluation give a bases of destruction extend nondestructive evaluation. Findings: The example gives an evolutionary acoustic properties of polymeric composite change illustration. It points the model diagnostic value. Research limitations/implications: In order to obtain reliable results, there are many factors to be considered such as real three-dimensional composite structure, type and quality of composite components, particularly reinforcement and others. Further work is needed in this area. Practical implications: The results obtained would be of considerable importance in the computer aided diagnostic method of polymer composite materials. Originality/value: A new approach to the problem of investigation of polymeric composite’s fatigue destruction has been demonstrated by means of computer simulation procedure. The method developed should be of interest to the industrial quality control applications and forecasting of important mechanical characteristics of composite materials, exploited in fatigue conditions.
