Fatigue failure of disordered materials / F. Kun, M.H. Costa, R.N. Costa Filho, J.S. Andrade Jr, J.B. Soares, S. Zapperi, H.J. Herrmann. - In: JOURNAL OF STATISTICAL MECHANICS: THEORY AND EXPERIMENT. - ISSN 1742-5468. - 2(2007 Feb 01), pp. P02003.1-P02003.9.
Abstract:
We present an experimental and theoretical study of the fatigue failure of heterogeneous materials under cyclic compression considering asphalt as a specific example. Varying the load amplitude, experiments reveal a finite fatigue limit below which the specimen does not break, while approaching the tensile strength of the material a rapid failure occurs. In the intermediate load range, the lifetime decreases with the load as a power law. We introduce two novel theoretical approaches, namely, a fibre bundle model and a fuse model, and show that both capture the major microscopic mechanisms of the fatigue failure of heterogeneous materials, providing an excellent agreement with the experimental findings.
