Prediction of fatigue crack rate in Al 7010 alloy with fibrous and recrystallized structure (in Czech)
vol. 36 (1998), no. 4, pp. 245 - 256

FEM elastic-plastic simulations of the fatigue crack growth in CT specimens made of Al 7010 alloy with fibrous and recrystallized structure under constant amplitude loading with the stress ratio R = 0.7 and R = 0 were performed. A comparison of theoretical and experimental results shows that the rate of fatigue crack growth in thin walled bodies made of this alloy can quite well be predicted from low-cycle fatigue of the material at the crack tip under plane stress conditions. However, the crack-tip cyclic plasticity under plane strain conditions is not very intensive and does not correspond with the high crack rate in the thick wall.

Key words
FEM elastic-plastic simulations, fatigue crack, Al 7010 alloy, fibrous and recrystallized structure
