Exact numerical solution for a time-dependent fiber-bundle model with continuous damage
L. Moral, J. B. Gomez, Y. Moreno +1
A time-dependent global fiber-bundle model of fracture with continuous damage was recently formulated in terms of an autonomous differential system and numerically solved by applyi…
Time dependence of breakdown in a global fiber-bundle model with continuous damage
L. Moral, Y. Moreno, J. B. Gomez +1
A time-dependent global fiber-bundle model of fracture with continuous damage is formulated in terms of a set of coupled non-linear differential equations. A first integral of this…
A model for complex aftershock sequences
Y. Moreno, A. Correig, J. B. Gomez +1
The decay rate of aftershocks is commonly very well described by the modified Omori law, , where n(t) is the number of aftershocks per unit time, t is the time…
Fracture and second-order phase transitions
Y. Moreno, J. B. Gomez, A. F. Pacheco
Using the global fiber bundle model as a tractable scheme of progressive fracture in heterogeneous materials, we define the branching ratio in avalanches as a suitable order parame…
Modified Renormalization Strategy for Sandpile Models
Y. Moreno, J. B. Gomez, A. F. Pacheco
Following the Renormalization Group scheme recently developed by Pietronero {\it et al}, we introduce a simplifying strategy for the renormalization of the relaxation dynamics of s…
Self-Organized Criticality in a Fibre-Bundle type model
Y. Moreno, J. B. Gomez, A. F. Pacheco
The dynamics of a fibre-bundle type model with equal load sharing rule is numerically studied. The system, formed by N elements, is driven by a slow increase of the load upon it wh…
