等载荷纤维束模型的细观描述

Mesoscopic Description of the Equal Load Sharing Fiber Bundle Model

Martin Hendrick, Srutarshi Pradhan, Alex Hansen

摘要:

等载荷纤维束模型的一个目的是描述失效事件的临界行为。实现这一点的一种方法是通过离散递归动力学。我们引入了一个连续的介观方程捕捉通过递归动力学发现的临界行为。它使我们能够将模型与传统上用于非平衡相变研究的吸收相变的统一框架联系起来。此外,它突出了相等的负载共享和调幅成核之间的类比。因此,这项工作是对纤维束模型的场论的追求的第一步。

英文摘要:

One aim of the equal load sharing fiber bundle model is to describe the critical behavior of failure events. One way of accomplishing this, is through a discrete recursive dynamics. We introduce a continuous mesoscopic equation catching the critical behavior found through recursive dynamics. It allows us to link the model with the unifying framework of absorbing phase transitions traditionally used in the study of non-equilibrium phase transitions. Moreover, it highlights the analogy between equal load sharing and spinodal nucleation. Consequently, this work is a first step towards the quest of a field theory for fiber bundle models.
