Abstract

Linear fracture mechanics gives possibility for assessment of the fatigue crack propagation. The difficulties in obtaining of the strict solution for stress intensity factor and uncertainties in results can be overcome by using a numerical calculation. The discussion on theoretical approach for part of such model is performed and captures of the screen of the computer program using this approach are plotted. 1 Introduction Commonly applied method for describing of the fatigue destruction of the construction appears the presentation of the number of the load's cycles to the given state of failure as a function of load level. In 1959 Paris [1] suggested that development of the fatigue crack
