纤维束模型中的合作动力学

Cooperative dynamics in the Fiber Bundle Model

Bikas K. Chakrabarti, Soumyajyoti Biswas, Srutarshi Pradhan

摘要:

本文讨论了纤维束模型中的协同失效动力学问题,其中单个单元或纤维是具有相同弹性常数但不同断裂强度的虎克弹簧。当光纤束受到应力或应变时,特别是在等载荷分配方案中,失效光纤所承受的载荷由其余幸存光纤平均分担。这种平均场类型的统计功能(没有波动)的负载分担机制,帮助主要的分析发展的研究中的模型和精确的比较与模拟结果的断裂动力学。我们打算对这些事态发展作一简要回顾。

英文摘要:

We discuss the cooperative failure dynamics in the Fiber Bundle Model where the individual elements or fibers are Hookean springs, having identical spring constant but different breaking strengths. When the bundle is stressed or strained, especially in the equal-load-sharing scheme, the load supported by the failed fiber gets shared equally by the rest of the surviving fibers. This mean-field type statistical feature (absence of fluctuations) in the load-sharing mechanism helped major analytical developments in the study of breaking dynamics in the model and precise comparisons with simulation results. We intend to present a brief review on these developments.
