Abstract The article considers the peculiarities of the model for predicting the crack resistance characteristics of pipe material taking into account the influence of corrosion-erosion processes during long-term operation with an estimation of one of the major characteristics of cyclic crack resistance, threshold stress intensity factor. A methodical description is given for the experimental determination of the values of cyclic crack resistance characteristics (threshold stress intensity factor, parameters of Paris equation of fatigue fracture kinetic diagram) of the pipe material under the direct corrosion-erosion effect of a liquid medium on fatigue crack front in laboratory compact specimen.
Keywords
