Purpose: The work deals with the principle of utilization of simulation models of fatigue degradation processes of composite materials as well as acoustic wave propagation for diagnostics of state of exhaustion carrying capacity of composite pipes. Design/methodology/approach: The basic aim of the assignment is working out the model of the propagation of the acoustic waves in inhomogeneous resilient resort representing the composite material, in the condition of acoustic diagnostic signal stimulation. Findings: The modelled analysis of the results of the process of the acoustic wave propagation with the use of material of thin-walled coating of pipe made of epoxy-glass, confirms the possibility the parameters of physical model of fatigue degradation process to be identified. Research limitations/implications: The dynamic load by course and distribution of surface corresponds to the cycle of the diagnostic impulse of the acoustic wave. Practical implications: The application of the procedure of simulation with reference to propagation of acoustic wave with identical period to models of various degradation level, allowed to seize the impact of structural features of the model on the speed of the wave propagation. Orignality/value: Paper is representing simulation models of fatigue degradation processes of composite materials.
