Purpose: In the work is described the method that enables identification of controller of simulation procedures which ensures compliance of experimental research results of changes in material physical characteristics with the characteristics of the numerical model. Design/methodology/approach: The work presents the method of diagnostic assessment of residual strength of composite pipes produced with the use of the method of winding glass fibre impregnated by chemically setting polyester resin, subjected to fatigue load in condition of pulsating fluid pressure. Findings: The basis of assessment is the correlation of residual strength with the acoustic characteristics of composite coating of the researched pipes. Research limitations/implications: The parameters of simulation procedures which are of key importance for correctness of diagnosis were determined on the basis of results of non-destructive and destructive testing of pipe material samples, subjected to the load in conditions corresponding the working ones. Practical implications: The diagnostic tool is the simulation program of degradation process of composite material with set structure, which enables investigating the changes in material characteristics for any operating load program. Originality/value: The paper presents a new approach to diagnostic processes of destruction aging-fatigue for the purpose of assessing the residual strength of composite pipes using computer simulation methods.
