[TTK] Bursts in a fiber bundle model of creep rupture

We present a theoretical study of the creep rupture of hetero-geneous materials based on a fiber bundle model where materialelements fail either due to immediate breaking or to a damageaccumulation process. We studied the time evolution of sin-gle bursts and found that they are composed of sub-avalancheswhich lead to a non-trivial temporal shape. The pulse shapeproved to be sensitive to the range of load sharing: for longrange interaction the average pulse shape is symmetric, how-ever, short range interaction leads to right handed asymmetry
