in Titre de série : | Physics letters A, Vol.184 No.6 | Titre : | Burst avalanches in bundles of fibers: Local versus global load-sharing | Type de document : | articles et extraits | Auteurs : | A. Hansen, Auteur ; P. C. Hemmer, Auteur | Année de publication : | 1994 | Importance : | p.394-396 | ISBN/ISSN/EAN : | 0375-9601 | Langues : | Français (fre) | Résumé : | Bursts in bundles of many parallel fibers with stochastically distributed failure thresholds are studied. The distribution of the sizes of burst avalanches has a power-law behavior, -. When the load is shared equally among surviving fibers, the power-law exponent is =2.5. When, however, the increased stresses that result from a fiber failure are concentrated to the nearest-neighbor fibers, the exponent is considerably higher, for randomly distributed thresholds =4.5.
