Avalanche dynamics of fiber bundle models Cruz Hidalgo, Raúl Kun, F. Kovács, K. Pagonabarraga Mora, Ignacio Mecànica de fractura Fracture mechanics Materials -- Fatiga Materials -- Fatigue We present a detailed analytical and numerical study of the avalanche distributions of the continuous damage fiber bundle model CDFBM . Linearly elastic fibers undergo a series of partial failure events which give rise to a gradual degradation of their stiffness. We show that the model reproduces a wide range of mechanical behaviors. We find that macroscopic hardening and plastic responses are characterized by avalanche distributions, which exhibit an algebraic decay with exponents between 5/2 and 2 different from those observed in mean-field fiber bundle models. We also derive analytically the phase diagram of a family of CDFBM which covers a large variety of potential avalanche size distributions. Our results provide a unified view of the statistics of breaking avalanches in fiber bundle models 2009 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/10256/7615 http://hdl.handle.net/10256/7615 eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevE.80.051108 info:eu-repo/semantics/altIdentifier/issn/1539-3755 info:eu-repo/semantics/altIdentifier/eissn/1550-2376 Tots els drets reservats info:eu-repo/semantics/openAccess application/pdf American Physical Society © Physical Review E, 2009, vol. 80, núm. 5, p. 051108 Articles publicats (D-F)
