Abstract

The problem of the propagation of deformations and stresses in a thin fiber under a dynamic mechanical load, as well as the destruction of the fiber, is considered. High-speed interactions in which the striker’s speed is comparable to the speed of sound in the fiber are considered. The numerical results are compared with an analytical solution for a point impact. Various loading modes are calculated for the distributed load on the fiber that cause significantly different types of deformations and destruction.

在动态载荷下模拟细纤维的变形和破坏

摘要

考虑了在动态机械载荷下细纤维中的变形和应力的传播以及纤维的破坏的问题。考虑到高速交互，其中撞针的速度与光纤中的声速相当。将数值结果与点冲击的解析解决方案进行比较。针对纤维上的分布式负载计算出各种加载模式，这些加载模式会导致不同类型的变形和破坏。
