@article{Materna_Oliva_2000, title={Computer Simulations of the Fatigue Crack Propagation}, volume={40}, url={https://ojs.cvut.cz/ojs/index.php/ap/article/view/140}, abstractNote={The following hypothesis for design of structures based on the damage tolerance philosophy is laid down: the perpendicular fatigue crack growth rate v in a certain point of a curved crack front is given by the local value of stress intensity factor per unit of nominal stress K’ and the local triaxiality T which describes the constraint. The relationship v = f (K’, T) is supposed to be typical for a given loading spectrum and material. Such relationship for a 2024 Al alloy and the flight-simulation spectrum was derived from the fatigue test of the rectangular panel with the central hole and used for three-dimensional simulation of the corner fatigue crack propagation in the model of the wing spar flangeplate. Finite element and boundary element methods were used for these computations. The results of the simulation are in good agreement with the experiment.}, number={4}, journal={Acta Polytechnica}, author={Materna, A. and Oliva, V.}, year={2000}, month={Jan.} }
