We show that in spite of the broad scatter of the Basquin exponent $\\alpha$, the fatigue fracture of heterogeneous materials exhibits intriguing universal features. Based on stochastic fracture models we propose a generic scaling form for the macroscopic deformation and show that at the fatigue limit the s","authors_text":"F. Kun, H. A. Carmona, H. J.
